ToME: the Tales of Maj'Eyal

...or the the talent is bugged.

A path of sunlight appears in front of you for 5 turns. All foes standing inside take 43, 58, 70, 79, 88 Light damage per turn. While standing in the path, your movement takes no time and can not trigger traps.

The problem with the description is that the path in itself does not give you any movement bonus. The no time movement comes from a magical effect you get when you cast this spell and then walk on the path. Why does this matter? Because while the path will be there for 5 turns, the magical effect necessarily isn't. It can be dispersed away completely or extented via timeless etc. If it's dispersed the path will still be there but it doesn't give any movement bonus whatsoever.

Dunno if the trap avoidance is a property of the path itself or the magical effect.

There doesn't seem to be any reason against making the walk_sun_path attribute into a passive of the talent, which would fix this problem. Nothing actually checks the temporary effect directly, they just check the attribute, and both places the attribute is checked also directly check that the relevant grids have a sun path map effect.

Forgive me for the necropost, but I made it to the final boss on Insane(Roguelike) today for the first time, and not knowing about this interaction until I came here confused was a big part of why I died.
