ToME: the Tales of Maj'Eyal

Giant Leap - Up the radius to 2, cut the cooldown down to 12.

YSBMW - Damage enemies you hit with the knockback too. So this becomes more like a nasty beam.

Massive Blow - I don't know, this thing kills me sometimes. It seems pretty strong but it is situational. Maybe swap the damages around (350% base and +150% if they hit a wall) so it's not so hamstrung by knockback immunity. Also can we cut the requirement down to 10 or 15 so it's not so tedious to get and occurs more often naturally?

Giant Leap is already pretty awesome IMHO.

YSBMW - could gain some synergy with Brawlers, maybe? Now that Grappling is usable.

Massive Blow could do more damage to bigger things, or do more damage to shielded targets (maybe enough to punch through one shield, guaranteed).
