Gloves of the destroyer

[Zechnophobe]

Actually is the bonus from items to spell damage additive with intelligence, or multiplicative? I thought it was the later.

So if you have 30 int (.05 * 30 + .15 * 4) = 2.1 times greater damage, does an item giving +20% make it 2.3 (2.1 + .2) or 2.52 (2.1 * 1.2) ?

When I see different sources for a bonus like that, I generally assume the latter, but that may be in error.
