ToME: the Tales of Maj'Eyal

Shadow Combat has a couple of harsh decisions that seem inconsistent with other similar talents:

1. As you put more points in it its mana cost actually increases. Almost no other spell or effect in T4 has an increasing cost as power goes up; and shadowblades in particular have mana problems at low levels. There are quite a few other 'damage-on-hit' talents in other classes (Ruin, Temporal Folding, Arcane Combat, etc.) and none of those have increasing resource costs. In fact, some of them don't have a resource cost at all!

2. Shadow Combat doesn't scale off spell power, which is a strange lack of synergy with Shadow Cunning in the same tree.

1. Body of Fire, Thunderstorm, and (kinda) mindslayer Auras, (and probably a few others that I'm missing) all increase in cost with more talent points, so it's not quite unique (though still rare, 6 talents out of about 500). I think that they all should be changed, to at least become more mana efficient, including Shadow Combat.

2. Agreed in principle, though it would be difficult to balance making it useful at low levels with it not being overpowered at high levels. Perhaps something like: which would give about 5 damage at talent level 1, 10 spellpower, and about 30 damage at talent level 6.5, 100 spellpower.
