ToME: the Tales of Maj'Eyal

Steamroller gives you a damage bonus + reset cooldown on Rush if you kill a rushed target in 2 turns.

Since my current character has Step-Up, extra Global Speed, extra Movement Speed and extra Combat Speed, I'm often not
too clear on when those 2 turns expire. I can see the cooldown reset, but can I see the 'current' damage bonus so I can
guess if I rush another shadow to build up more bonus or go after the main Boss? I would have expected it in the mouseover
on the Rush talent icon, but that stays at 120% damage.

I'm surprised it isn't it the buff bar. Maybe it's in your charsheet as +50% (or 100) all damage?

It's in the character sheet, alright. But that is kind of confusing, because lots of talents change things in there and it's always compared to the last time you look, not the 'baseline' without any talents active.

The stacking damage bonus? That should be in the buff bar; the icon looks kinda like the logo thing on recycling bins.

It's in the list when I press m, but it's a passive talent - how do I get the icon to the screen?

Buff bar, not hot bar.

I'm almost positive that this buff is shown in the buff bar on the right side of the screen. Same place as all your sustains and other temporary buffs like shields and whatnot.

Now I'm glad I posted this in Dumb Questions - I hadn't noticed something happening at all on the right of the screen. Interesting!

It's also a debuff on the targeted creature. The one you have to kill quick to keep it going.
