Halicar, the Sage of the Sands

#Lore
Halicar was one of the first Shuriman Emperors and one of the first Ascended. Ascending into form of Snake, he manifests his eternal life full of unending knowledge and the most ancient secrets of healing by travelling through Shurima and helping to tend to wounds of both men and Shurima itself, though one should not mistake these acts of benevolence as defining Halicar as kind being, as he only does what ages of learning are showing him to be the best fate for Shurima and he earned such vast knowledge through his cold-hearted pragmatism.
#PASSIVE: Wisdom of the Sage
Every champion takedown, every 20 minions or monsters killed and every epic or legendary monster takedown grants Halicar 5 Base AP.
Halicar's abilities scale either with Base AP (only the AP gained via this ability), Bonus AP (traditional income) or Total AP (both).
#Q: Dunecaller 60 / 70 / 80 / 90 / 100 Mana 12 / 11 / 10 / 9 / 8 sec Cooldown
Halicar starts channeling, being able to only move for up to 2 seconds. After the 2 seconds or upon free reactivation, he summons a dune in distant targeted medium area. The dune inflicts 20 / 30 / 40 / 50 / 60 (+15%Bonus AP) plus [ 10 / 15 / 20 / 25 / 30 (+5%Bonus AP) per second of the channel ] Magic Damage each second ( Max 40 / 60 / 80 / 100 / 120 (+25%Bonus AP) per second, up to 160 / 240 / 320 / 400 / 480 (+100%Bonus AP) ) and slows by 5% / 7.5% / 10% / 12.5% / 15% plus [ 1% / 2% / 3% / 4% / 5% per second of the channel ].
The dune lasts for 4 seconds and leaves behind Snake Nest.
#W: Desert Hermit 80 / 85 / 90 / 95 / 100 Mana 14 / 13 / 12 / 11 / 10 sec Cooldown
Passive: Champion takedowns leave behind Snake Nest. Movement Speed increased by 6 / 8 / 10 / 12 / 14 when moving towards Snake Nest.
Active: Halicar shields himself for up to 4 seconds absorbing up to 80 / 120 / 160 / 200 / 240 (+200%Base AP) damage. The Movement Speed bonus towards Snake Nests is doubled while shielded this way.
#E: Slithering Ambush 40 / 50 / 60 / 70 / 80 Mana 10 sec Cooldown
Sends towards target a snake from Halicar and each nearby Snake Nest, consuming them. Snake affects the first enemy hit, dealing 60 / 100 / 140 / 180 / 220 (+80%Total AP) Magic Damage and rooting for 1.5 seconds. An enemy can be hit by multiple snakes, but only affected once.
#R: Rod of Ages 150 Mana 160 / 125 / 90 sec Cooldown
Halicar charges his Rod with Water, healing himself, gaining Age stack and then charges the Rod with Fire.
If the Rod is of Fire, moving near enemy champion deals them 80 / 120 / 160 (+40%Total AP) plus 20 / 40 / 60 (+20%Bonus AP) per Age stack Magic Damage, grants Age stack and charges the Rod with Water.
If the Rod is of Water, moving near allied champion heals them for 40 / 60 / 80 (+10%Total AP) plus 10 / 15 / 20 (+20%Base AP) per Age stack, grants Age stack and charges the Rod with Fire.
The Rod loses its power when Halicar fails to damage or heal champion within 10 seconds or at 6 Age stacks.
Thus, Halicar switches between damaging and healing champions, where the damage and heal gain in power based on how many times Halicar damaged or healed this way. Halicar can damage up to 3 times (Max 1020 (+120%Total AP) (+180%Bonus AP) damage) and heal up to 2 times (Max** 280 (+20%Total AP) (+120%Base AP)** healing), excluding the 40 / 60 / 80 (+10%Total AP) self-heal.
