kapusta11: Sustained Glyph skill:

I take it description is misleading, the amount of basic traps should obviously be higher than that of alternate mode (4 magic traps would be broken). In addition and what is more important, the amount of charges is lower than what it should've been. Number in brackets is what description supposed to say.

Rank 1:
Basic trap charges 1 (2), magic trap charges 1 (1), the latter requires Magic Trap skill unloked, obviously
Rank 2:
Basic trap charges 2 (4), magic trap charges 1 (2)

Duration appears to be fine

Magic Trap skill:
Rank 2 and 3:
No damage increase (25 and 50%) based on stats and damage inflicted upon monsters (still the same). Base damage varies for some reason in 128-131 range.

Stuff like Melt Armor is hard to test and that is all skills I've unlocked so far, playing on Death March difficulty, awesome game overall but skill tree needs some polishing. Hopefully devs will read this thread.

ChevyNoel: On the topic of skills, I've noticed that my 10% sign mutagen gives a 30% intensity bonus when I load a save. If I remove the mutagen, then re-equip it, I get a 40% bonus.

It seems that loading a save multiplies the bonus by the number of attached skills, while equipping a mutagen gives its own base %, and adds that % again for each attached skill.
