Gloves of the destroyer

What does the combo give you? Is it worth it?

[DGDobrev]

A good question.

The combo artifact gives +20% to the power of all spells and +10% fire, magic, poison and astral resistance.

In general, 20% power is like +4 intellect (4x5%), but as a mage, it is better to stack up on intellect rather than spell power due to the 7-point bonus of 15% (as you know each 7 points of intellect grant an additional +15% spell damage bonus). The resist bonuses are nice, just be sure to dismantle the artifact if you need magic or astral resistance in the upcoming battle.

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.

[DGDobrev]

I also assume the latter. In KBAP calculations seem to be additive rather than multiplicative. I am uncertain as well but most fof the formulas are based on that, so logic dictates that this one is based on that as well.

I wish I hadn't completed all my mage games so that I can check which is better - +3 int or +15%, for example.

I just checked, and it seems its the latter..

I have a 44 intel mage right now, and I just bought the Crystal Helmet (+10% dmg), for the obvios reason of destroying it.
However I switched my poor Wizard's Hat for the Crystal helmet. In direct comparison it means I dropped to 42 intel but added 10% dmg.

I'm not a math student, so I'll leave the details to you guys, but my Fire Rain went from 3320-3795dmg with 44 intel to 3430 - 3920 with 42 intel and 10% dmg increase

Note that the difference could be even higher with more intel, or if I had no points in destuction (Which is maxed)

[DGDobrev]

Most interesting. -2 intellect should equal +10% damage increase if the formula is additive, but there seems to be about 3% difference between the minimum and maximum damage values.

[Zechnophobe]

So, it looks about right (Did you have destroyer skill?)

You'd be 3.1 times normal damage with 44 int, and 3.3 times normal damage with 42 int + 10%. So that means that we multiply the bonus' together instead of adding them. That actually means that they are a fair bit more effective then they look.
