Gloves of the destroyer

[Metathron]

I have two pieces that are supposedly part of this set - the crown of chaos and the student's belt, but there does not appear to be any info on the complete set. What gives?

[DGDobrev]

The part you're missing is the fire master's bracers. If it is present in your game and you find it, you will be able to assemble the combo artifact.

[Metathron]

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.
