Evoker - Support Ottermancer - MetaBattle

General

Under General Options / User Interface enable "Thick party health bars" and "Always show health bars". These will make it much easier to keep track of who needs your support. For more tips check out our settings guide.
This build is designed around 特长元素. As such, you will not have the same flexibility (or complicated plays) as a normal Elementalist build. This does mean that you can 'run out of gas' if you're not careful, but timing your abilities is one of the biggest components of skill expression when playing this otherwise relatively simple build.
Water specialization (Otter) grants you a passive ability which heals allies for a small amount when you grant them regeneration. It may not look like much, but it adds up!
Avoid getting locked into 1v1s, always be in teamfights. You depend on your allies just as much as they depend on you! A support's job is to keep party members alive through support, and these allies must peel for you in return (if the enemy team gets to focus you without allies counterpressuring them you'll probably end up dead).
Nearly all of your skills require close/melee range. Try to stay right on top of your team to make sure your skills can reach them.
At game start, during countdown, use 冰锥喷射 + 净化水波 to charge up 溅射冲击, cast it, then cast 冰霜光环 and 冰封爆裂 to charge it again. This should let you get a 洪水倾泻 early into the first fight.
Use 溅射冲击/洪水倾泻 off cooldown to maintain 魔宠威勇 and 活力 (from 魔宠祝福).
复苏回春 is not normally a support heal, but it serves as one for this build:
Thanks to 利他倾向, it grants 圣盾 to nearby allies.
Relics such as 流水古物 trigger for additional ally support effects.
grants you , which is then shared to nearby allies with . This, in turn, grants affected allies thanks to .
Because it fully charges /, you can cast them immediately after for a heal that will also grant nearby allies thanks to .
As such, try to use it when you have no familiar charges, such as right after using your familar skill.

Crowd Control

Your sources of CC are:
from with .
In lieu of a large amount of hard CC, you want to focus on reapplying as much as possible to enemies to keep them "soft-CC'd" for the fight. In longer fights, this will turn into a big advantage for your team due to enemies running out of cooldowns, etc.
