Grasp should be procced by abilities. That would make more sense in my opinion. especially since conqueror already beats it in every way, unless you have 
amounts of health.
And not to mention it's like the weakest rune in the green tree.
Edit: Just some math with gras as it stands for melee users for dmg.
1k hp= 40 MAGIC damage 2k hp= 80 3k hp= 120
For ranged users.
1k hp= 24 magic damage 2k hp= 48 magic damage and so forth.
Sire Hippington11 votesIf grasp needs any change, then it's lowering the damage a bit and increasing the heal, which would be more fitting for a tank rune and would set it further appart form conqueror which is the prime DAMAGE rune for prolonged fights.
MrFawknSunshine1 voteswell the damage is directly reflected of the champs HP
the less hp the champ has the less damage it does
PASSIVE: Dealing or receiving damage within 2 seconds generates one stack every second. At 4 stacks, your next basic attack within 6 seconds, against an enemy champion deals 4% of your maximum health bonus magic damage, restores 2% of your maximum health, and permanently grants 5 bonus health. The empowered attack duration refreshes whenever dealing or receiving damage. On Ranged role ranged champions, the effects are reduced by 40%, down to 2.4% of your maximum health, 1.2% of your maximum health, and 3 bonus health respectively.
so its 4% of max hp as magic damage which is reduced by MR
if the champ has 3000 hp it does 120 damage if the champ has 1000hp it does 40 damage
so its 40 damage for every 1000 hp for melee champs
for ranged champs its 24 damage for every 1000 hp
so its not doing a lot of damage. its less then an auto attack til you reach close to 3000 hp

ModWulf Helhammer7 votesConqueror doesn’t beat grasp in terms of giving you defense.
Grasp isn’t supposed to be a damage rune. It does some, yes, but that’s not the reason for it.

True, but as it stands. Top lane is tanks vs bruisers. I think throwing tanks a bone would benefit them and wouldn't break top lane.
Serge THE GREAT6 votesGrasp isn't a damage rune, sure, but the 'defense' it gives you is garbage. Most top lane characters that are meta have built in poke, escapes and CC and if you are against them you are probably barely every proc'ing Grasp. So what's the point? You're always better off going for a damage based Keystone or Aftershock if you have CC.

Don't know why people are downvoting you, this is correct.
Also TBH I don't think this change would be a good idea due to the amount of ways it could be abused... what about champions like 
that are already oppressive enough as it is, without being able to proc Grasp with ranged abilities that cost pretty much no mana.
MrFawknSunshine1 voteswell if it proc on his Q
it is only 24 magic damage per 1000 hp for range
rayzo1 voteswell if it proc on his Q
it is only 24 magic damage per 1000 hp for range
That's not the point. It % heals him, deals % damage, and stacks infinitely.
MrFawknSunshine1 votesbut it gives reduced healing and perm hp on range champs
Sire Hippington1 votesas it stands, it's on ranged CHAMPS, not ranged abillities, so pant would get full value just how GP and poppy atm get full value despite procing it from range.
Sire Hippington1 votesit might not be supposed to be a damage rune, but atm it is, the damage ratio is twice as high as the healing ratio and the max hp you get is VERY matchup dependend. you don't pick grasp to be hard to kill right now, you pick it to have strong trades in lane.
Bisaknosp5 votesthe most needed change is this fucker 
not being able to gain full benefit for his disgusting q spam
Moody P2 votesgrasp is busted as is and you think it should be buffed???
MrFawknSunshine1 votesbusted how ?
Moody P2 votesstrong damage and healing that adds up quick, it's easily the best laning rune in top across the roster
MrFawknSunshine4 votesyet is only 40 damage per 1000 hp reduced by magic resistance
where as conqueror gives AD and converts 20% of damage to true damage which cant be reduced by any defensive
Moody P2 votesHow much HP do you have in early laning? We aren't talking about how well it scales because it's not meant to scale, but it's base in the early is much more useful than Conq unless you go into a long trade
MrFawknSunshine2 voteswell at lvl 1 maokai ( a champ who would take grasp ) has 595 hp lvl 1
so what is 4% of 595? 24 so it does 24 magic damage all champs start with at least 30 mr
so how much damage would it do to a target that has 30 mr when its damage is 24 ?
ITS SO BROKEN
[zombie-brand-facepalm]
Sire Hippington1 votesIn one AA every 4 sec
What does conqueror do for you at that point? 6 ad and not to much value from the truedamage unless you're oponend goes full armor runes+cloth start, and that only AFTER the first AA, so in most trades, you gain maybe ~12 damage from it, which is less than the damage from grasp, which also heals.
Also for the poke example, aery does about the same damage, but without heal nor the increased damage in melee with a similar CD.
Electrocute does 30 damag lvl 1 for a full combo, so barly more than grasp on a melee AA but with 6times the CD and without heal.
Besides full all-ins, Grasp is the superior rune for early laneing. It just gets outscaled rather quickly by conqueror for extendet duels while shareing it's issue of needing 4secs in combat to do anything.
MrFawknSunshine1 voteshow much damage do u take from grasp that gives 24 magic damage when a target has 30 base mr?
Sire Hippington1 votes~18.5, and the other keystones have their damage reduced by resis aswell.
MrFawknSunshine1 votesnot conqueror the true damage cant be reduced by anything
Sire Hippington1 votesit's 20% of you're damage that gets converted, which is quite siginficant later on, but not that much off a difference early with values of 30-40 armor. The more impactfull part for the early lane is the bonus ad, and 80% of that is reduced by armor. Also, even without reduction, conqueror adds less damage than grasp with reduction for most trades. There are exeptions that can open with an AA and have enough ad ratios in their tradeing combo to have conqueror out damage grasp like Renekton, but for most (melee)champs, grasp is the superior rune for early trades.
MrFawknSunshine1 votesgrasp dont give bonus ad like conqueror does that enhances all abilities that scale on ad and auto attacks and it dont grant true damage.
the damage from grasp is directly related to the champs max HP and the healing is also directly related to this. the damage from grasp never out scales the mr in game and is useless outside of lane phase for the most part.
when conqueror give 10 bonus ad that is a long sword worth of damage for free + the true damage
conqueror at all stages out damage/scale grasp
ModAcademy Kayn2 votesNo. I don't need more GP or Poppy pokes with grasp.

Meh. is better off going conqueror because that true dmg is going to help his Q's a lot more.

Meh.
Conqueror is better suited for extended trades, which Pantheon does not excel in. He also needs to land a basic attack on the enemy champion first before it triggers, meaning it doesn't actually help his Q poke all that much.
Grasp of the Undying (if the change you're suggesting gets through), however, is a poke Rune that's up every 4 seconds, which fits perfectly with Pantheon's Spear Shot that has a flat 4 second cooldown.
It also grants him a nice amount of bonus health, which Pantheon can always benefit from, seeing as most of his builds are just pure AD items with very little defense.
Tahminatrix 1 votesDon't let the devs touch grasp, they are just going to give it the overgrowth treatment.
Itl do flat damage and flat healing that barely scales at all with your hp and will overall do less for a tank and more for a squishy carry, lol.
Anchorit Wracaj1 votesStop buffing damage to Grasp... Lower the damage by half.But increase the healing+double the health gaining.Instead of 5 go to 10.
MrFawknSunshine1 votesgrasp dont do a lot of damage
