Bug reports.

[Katajiro]

1. Sorceress skills Cast on Freeze, Cast on Shock and Cast on Ignite don't work even if you have enough spirit to reserve.
2. Temple of Kopec: the checkpoint marker at the boss fight doesn't work - if you die, you will get teleported to the checkpoint at the level start. If you try to use the checkpoint to teleport to the boss checkpoint, you'll be teleported to the beginning of the level instead.
3. This is more of a gripe than a bug: using the sorceress skill Lightning Warp (not sure if the same issue is present with other culling skills) cancels all boss death animations and makes the victory anticlimactic when only the sound and dialogues of side characters remain. Example: the first act final boss will writhe in agony and engage in a dialogue with the Hooded One in a cut scene. If you instakill the boss with the Lightning Warp, you'll only have voices in an empty room.
