Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Annoying Bug leading to huge exploit.

Have successfully reproduced this in combat.

Playing Knight build with Fire/Air magick and Lone Wolf trait (so can collect enough AP).

At first mentioned that trying to use Battering Ram and then prepare Dust Devil usually ended that AP used double as Battering Ram. Accidentally when trying to hit door with magick and prepare next skill out of combat executed double cast.

Next test observations:

1. Man-at-Arms skills do not activate new animation but damage persist (replicated on 2x Dust Devil, in combat).
2. Magick skills animation works fine for each next attempt (2x Ice Shard from ring, have no Hydrosophist).
3. Buff skills seems cannot be doublecasted.
4. Cannot doublecast AoE Self Immolation (if I correctly remember skill name).
5. Successfull 4x cast of spell out of combat.

P.S. Think this can be mentioned as exploit since can be doublecasted on skills with high cooldown (5 turns Dust Devil)
