Something seriously wrong with Mana Shield

[adeyke]

With 12 points into Telekinesis, I have a 75% effectiveness in my damage to mana ratio, making ES only shave off 1.25 mana per point of damage absorbed. To put it into context, I have a 1 : 1.25 Ratio of damage absorbed going to mana.

With 135% damage goes to mana, this would effectively make the ratio 1 : -0.10. To put that into context, I should be gaining 0.1% of the damage I take into mana.

Here is my problem: I'm loosing mana at a rate consistent with not having either Telekinesis or Damage Goes to Mana. I haven't done extensive testing to figure out which is the culprit, but I have tested this phenomenon in normal cows by putting up Energy Shield then letting the cows hit me. I saw my mana go down! Hell Bovines in normal do 27-43 damage, or 35 average damage. I lost approximately 21.75 average mana per hit from a cow over 20 consecutive hits (the least was 14, the most was 42). If the most was 42, that means I’m getting almost 100% damage goes to mana, or 1:1. This doesn’t make any sense!

No. The % damage taken goes to mana works on the amount of damage you take, while the mana loss is based on the amount of damage absorbed.

If a monster deals 27-43 damage (is this actually right?), a 74% ES will absorb 19.98-31.82 damage, leaving 7.02-11.18 damage. With 12 points in TK, you're losing 1.25 mana per point of damage absorbed. So you're losing 24.975-39.775 mana per hit. However, you're also gaining 1.35 life per point of damage taken. So you're gaining 9.477-15.093 mana per hit.

That means that, for very 27-43 damage hit, you're losing 7.02-11.118 life and 15.498-24.682 mana (average: 20.09). This seems to match your data rather closely. Inaccuracies may be attributed to rounding issues, mana regeneration and/or critical strike (in the case of the the 42 mana loss hit).

(There's also the matter of % damage taken goes to mana only working with physical attacks and ES coming before resistances, but these don't matter here, since you were hit by a physical attack and presumably had no physical resists).

If you do have 12 points in TK and a 74% ES, you'll actually need 214% damage taken goes to mana to break even and lose no mana.
