ToME: the Tales of Maj'Eyal

I don't understand why my crit mult seems to drop from 175 to 150% every so often without me changing any gear or removing sustains. Is there some trick when leveling or transitioning?

Is this on every character or just specific characters?
It probably a talent doing it, but we need a hint about which ones you might have.

I've only noticed it on my archer, who has a pretty decent crit chance, and I have that prodigy pain enhancement system, have what I guess are the usual sustains up (aim etc) and venemous ammo because I like the leech. I'm always looking for ways to increase crit mult because I crit often, that's why I don't understand the drop back to default 150.

Well I can't see anything on your character (Except for the Bethelen leather armour) that even gives increased critical damage.

I can't remember having changed boots, but I think it was those, I must have been wearing "fulagerosus" which gives +25% crit mult and otherwise nothing much :/

Now I understand what must be happening.
On my hotbar I still have this activated skill (random teleport) from the boots I am NOT wearing. I must have clicked that button, which also does NOT activate the skill but instead puts the boots on (sadly I still have them in my inventory). Argh!!!
