Energy Shield[edit]

Required Level: 24
Prerequisites: Charged Bolt, Telekinesis, Lightning, Teleport, Chain Lightning
Synergies: Points in Telekinesis boost the effectiveness of Energy Shield, decreasing the absorption by 6.25% per point. (See below.)
Details: Energy Shield allows the Sorceress to redirect damage from life to mana. Instead of attacks costing her life, some % of them (increasing with more points in the skill) will subtract from her mana instead.

• The use of this skill varies a lot between Sorceresses. Since only a % of the incoming damage is redirected, this skill needs a fair amount of points to be useful.
• High hit point or low mana builds will find this less necessary or useful.
• Telekinesis improves this skill by making the damage absorption more efficient. By default, each point of damage redirect to mana consumes 2 mana points. So with lvl 7 Energy Shield absorbing 50% of damage, 10 points of damage would take off 5 life and 10 mana. If that same Sorceress had 8 points in Telekinesis, the mana cost would be cut to 7.5 mana. With 16 points in TK, the mana loss would only be 5, a 50% decrease.

FAQ[edit]

Q: What does telekinesis do for energy shield?

A: Energy shield takes 2 points of mana for every point of life it absorbs. Each point you spend in telekinesis reduces this by 0.0625 point. This means that after 16 points you’re only losing half the mana compared to zero points, or one mana per absorbed life. At 20 points you’re only losing 0.75 mana per absorbed hit point.

Q: So if you get a level 32 telekinesis you’re losing no mana through energy shield?

A: No, it only works with actual invested points, so level 20 (1:0.75) is the limit.

Q: How much damage can energy shield absorb?

A: It’s capped at 95%, which is at skill level (slvl) 40. After that only the duration of energy shield increases.

Q: What is the energy shield bug?

A: It doesn’t exist. This ‘bug’ you might’ve heard about, is simply an intended change from blizzard. This change is that energy shield is now applied before resistances, meaning your mana gets drained four times as much as it used to with maxed resistances. Telekinesis doesn’t totally make up for this, but it helps.

Q: Is energy shield applied before the PvP penalty?

A: No. This is good since this means 6 times less mana draining.

Q: How do I calculate damage taken to mana and life with energy shield?

There’s a formula for that:

Damage to life = InitialDamage*(W/100)*(1-X/100)*(1-Y/100)*(1-Z/100)

W = PvP penalty (for most, if not all attacks 17%)

X = % resistance (or damage reduction in case of a physical attack)

Y = % chance to block (in case of a physical attack or blockable elemental attack)

Z = % energy shield

Fill in zero if you have zero resistance or block or damage reduction.

For example if you take 12,000 damage hit from a fire ball when dueling another sorceress with maxed telekinesis, resistances and 95% (max) energy shield:

Damage to life = 12,000*0.17*(1-0.75)*(1-0)*(1-0.95) = 25.5 life lost

For damage to mana another formula can be used:

Damage to mana = Damage*(2 – 0.0625x)*(W/100)

x = slvl telekinesis W = pvp penalty

Take the same example as above, with the fire ball hitting:

Damage to mana = 12,000*(2-0.0625*20)*(0.17) = 1530 mana lost

Q: Is damage to mana % effective in combination with energy shield?

A: No. Since damage to mana is now subtracted from the actual damage you take, in our fire ball example, it would take (1,500/25)*100 = 6,000% damage to mana in order to restore the lost mana. The higher your energy shield gets, the less you benefit from %damage to mana.

A formula for this is: Damage to mana/Damage to life*100 = Amount of DmgToMana% needed to fully restore lost mana

Q: Is Energy shield viable?

A: Yes, this build is very powerful in both PvM as in PvP, the main problems are getting enough damage output, and mana burn monsters in PvM.

Q: I don't get all this math, in simple language, what can ES do for me?

A: It can absorb 95% of all damage you take, given that you can keep your mana high enough. Your lost life will be very minor, but your mana takes heavy beat. Telekinesis helps reducing the cost of mana.

Q: Does energy shield absorb all attacks?

A: No, it doesn't absorb poison and open wounds. There's also reports of a bug where it doesn't absorb charge either.

Input (still) very welcome, when constructively and at least somewhat nicely brought.
