DFG left a niche that Liandry's doesn't fill
#The Problem There isn't any item in the game to help a burst caster deal with health stacking. Liandy's is only good if you're consistently applying it. It sucks for champions that need to put out one combo and blow someone up with that one combo. DFG helped there. With it gone, there's nothing burst casters can do. But DFG should not comeback as it was.
The problem with DFG was that it blew up tanks and squishies. Why? Percent max health damage is incredibly strong against anyone. It doesn't matter how much health they have, a 30% nuke is 30% of anyone's health (it's actually less effective against tanks because they have more MR).
#My solution Before I put out my solution, something needs to be released to fill that void. I'm just throwing something out. Whatever it is, the item should be effective against high health/tanky champions, but very ineffective against squishy champions.
Deathfire's Grasp -> Blasting Wand + Blasting Wand + 400g 80 AP Unique Passive: Your spells gain (0.015 x Enemy Bonus Health)% magic penetration. Unique Active: Deals 200 + (40% of a target's Bonus Health) magic damage. 90 second cooldown.
#Why I chose these stats/effects:
**General design - **For a burst champion, this item should be exceptionally powerful against tanks that would otherwise be impossible to deal with, but have very little effect on anyone else. When you buy this item you're basically saying "I'm buying this because I need to focus my build on you and you alone." To that end, it should be OK if it's strong against that kind of champion, as long as it's junk against everyone else. Think niche pick like Thornmail; It's only strong against auto attacks, but it supplies enough armor to not be 100% useless against everyone else. This item really isn't too effective until the tank reaches raid boss status either. **AP - **There isn't a ton. It's a good contribution to your AP, but there are better choices out there damage-wise. This makes it less effective against squishy champions, but not worthless. **Passive - **Yes, this stacks additively with void staff, but it scales off of enemy bonus health with no base amount. Against a champion with little to no bonus health this passive is utterly worthless by design, yet it's very effective against someone with a lot of bonus health and MR. If your opponent has 2,000 bonus health (probably around 4.5k total) then together with Void Staff you'll have about 75% magic pen. Yes, that's absurdly high by design. **Active - **Unless you have a boatload of AP you're not going to deal 4.5k damage in anything resembling burst. The best way to deal high damage is through percent health, but then we're back to the old DFG. The difference here is that it focuses on bonus health. Against someone with 2,000 bonus health you'll get 1,000 damage out of the active before resistances are applied. Again, absurdly strong by design, but only against high health champions. Against someone with 200 or so bonus health you'll get 240 damage from it before resistances. It's something, but not worth the gold investment.
The biggest downside I can think of with this is if someone who deals consistent magic damage buys the item, like Cassy or Azir. They would melt tanks with this item. That might be OK as long as they're ineffective against squishies.
#TL;DR Burst casters can't deal with tanks and need an item that is only effective against tanks. Liandry's doesn't fulfill that niche for burst casters.
