Gimme your top tips when playing lock.
The demon management is bit clunky, I found useful to bind Demon Bind and Consume on something like F7/F8 keys away from other keys, so it is not pressed accidentally and lose Hepha.
It is probably good idea to put keys next to each other in sequence.
Spawn defiler, spawn tainted, consume tainted - F6/F7/F8 or something sequential next to each other.
When you want to buff yourself with Bonus from Tainted for example, it is good to do it opposite way you are running or basically somewhere in screen corner so you do not consume your binded Demon.
Buffing demons - death mark needs target to get the bonus and Engorge it is probably not very visible after certain level 90+, eni etc. If they nerf binded demon defenses we might need to use Engorge more.
