Dark Seer Skill Strategies
Here are some tips on how you can improve in playing the skills of Dark Seer - Ish'kafel. Each skill is given some general tips on how to use them more effectively.
Vacuum
Your only direct damage nuke with a helpful moving feature.
Pull back a running hero. If he's running and you're behind him, you have to have good timing. You should get used to the cast range and the AoE. Both are big enough, but when a running hero is quite close to you and you aim vacuum wrong, you may even help the enemy escape.
If the running enemy is quite near, cast vacuum literally on yourself. He will be dragged right to you. If he is further away (not in the distance to be able to pull him to you) you have to predict where he moves. Cast it right on him and since it's not instant and he's running, when the pull occurs, he is approximately and the edge of the AoE, causing maximum pull and therefore increasing the chance of catching him.
In farming, when coupled with ion shell, you can use vacuum to drag all enemy creeps exactly on the shelled unit, utilizing shell even more.
To get a kill. Vacuum enemies to a friendly stunner. Works perfectly.
Ion Shell
Your biggest damage output. Remember that this doesn't damage the unit it is cast on. Shell should be cast on friendly melee heroes with stun, but other heroes can utilize it too (ranged tanks against a melee team).
To get a kill, cast together with surge on a friendly hero to ensure a huge damage output.
For jungling, you should permanently have shell when jungling. Never forget it. Since it does much more damage than vacuum, always max it when jungling. Shell won't be dispelled by purge, so don't fear the satyrs.
Surge
Great support skill. This 6.5 second haste can save heroes and help get a few kills.
For travelling. It can get you quicker anywhere you want. Use it always when going to the fountain. Since it doesn't cost tons of mana, you can spam it once you have a few mana items.
Wall of Replica
This is your main pushing skill. Cast it on the cliff to the base. Tell your teammates to run through. Select all images and attack.
For defending, cast it again on the cliff. If the enemies want to destroy the tower, they will run through and the images will slow them down.
For distraction. Cast it in the forest with all your teammates, send the images to a fake gank and push the other side. You need a good team for this.
