[quote="Gandelf"]Here is one quote from the link, which I thought was in error:-
I do overcharged templates all the time and I certainly don't use 4xMP gems on one item. Usually, most overcharged items I imbue have 1x98% gem and 3x99%. I've even tested imbuing something myself using 2x98% and 2x99% gems and that was on a 99% quality item, with a 5½]
Ahh, they probably are using the official formula from
here
The formula is:
Overcharge penalty
0: 0
1: -10
2: -20
3: -30
4: -50
5: -70
Gem Quality Bonus (per gem)
96: 1
97: 3
98: 5
99: 8
100: 11
Item Quality Bonus
96: 6
97: 8
98: 10
99: 18
100: 26
Spellcrafter Skill Bonus
5*(floor(Skill/50) - 10)
e.g. floor(1005/50) = floor(20.1) = 20
so the bonus would be 5*(20-10) = +50
So a 1001 crafter with 100% everything and 5 overcharge works out at
OC: -70
Gems: 4*11
Item: +26
Skill : +50
total: 50%
Anyway, it seems like Mythic decided that that was to traumatic for people to lose 99/MP items. The rule of thumb was that anything above 30% chance of success is safe.
Maybe they decided not to apply the overcharge penalty.
In any case, can you imagine what it would have been like if they kept the official chances. Customers would be demanding MP gems (and not getting them

). With 99% gems, the chance would be 38%. This means that people who want MP gear would take an average of ~2.5 items per slot. This would generate alot of buisness for crafters with remakes. A 5 point OC on a 99% item would be 30% chance of success, so going the cheap route actually means more likelyhood of blowing up.
