So, most mods that had "Charge speed" or "charge damage" have now been replaced with "Channeling efficiency" as a stat.

What does Channeling efficiency do? When it says "+30% Channeling Efficiency", what exactly is happening? Does it mean it costs less energy per melee hit while channeling, does it mean I get more damage out of channeling, does it have any other effect?

Channeling Efficiency reduces the cost per hit while channeling (holding left mouse button while having the sword equipped).

Base cost is 5 energy per hit (misses do not use energy), minimum energy cost is set to 1 Energy per strike, so even if you should get 100% channelig Efficiency, you can't get below that cap.

Also not that you can gain a damage multiplier while chanelling - ever 5 consecutive hits earns you a damage multiplier of 0.5 (I don't know if there is a cap).

  • so what's my best bet for Channeling Efficiency in terms of limits? For example, p efficiency is limited by 75% or 65% i believe, so going over doesn't affect energy spent anymore, what about channeling? Is it 100% as a cap?

  • As per the wiki - Power Efficiency is capped at 80%, which translates to 1 energy per hit while channeling.

Channeling happens when you hold down the left mouse button while in melee mode, and (at base) converts 5 Energy into extra damage on your next melee hit.

Channeling Efficiency reduces the amount of energy each hit consumes to a minimum of 1 Energy per hit, so "30% channel efficiency" would mean your attacks consume 5*0.7=3.5 energy per strike.
