Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Endgame spells underwhelming

That's silly. You could kill almost any boss in a single turn by hitting them with isolated AOE spells.

It also goes against the idea of AOE spells - they're supposed to be less efficient unless you're attacking multiple targets.

And you're wrong in thinking that they're not worth using. Dealing 1000+ damage total to the final boss with Hail is totally worth 9 AP, when the level 2 Icicle spell (whatever its name is) only deals around 400 damage for 6 AP.

Looked up the numbers. With 20 Intelligence,
Piercing Ice Shard costs 6 AP and deals 222-234 ice damage.
Hail costs 9 AP and deals 441-539 ice damage PER HIT.

That means that if only a SINGLE PROJECTILE hits, Hail was worth the AP cost.
