ToME: the Tales of Maj'Eyal

Using the Summertide Phial to light up the darkness still leaves the tile that you're standing on unlit. I think wands of illumination may not have this issue, but I'm not 100% sure (hate wasting expensive wand charges). I haven't tested an archmage's illumination spell lately, or paladin/anorithil's blinding light.

Good catch, the friendlyfire needs to be set to true in Summertide's use_power function.
