Your favorite mob to enslave is...Follow

The title says it all. Share the demon(s) you like to enslave for whatever reason.

For me, it's probably the Fear Fiend of Forge Camp: Terror in Blade's Edge mountains. It's a flying mount only area. The fiend has a cone breath attack (Fel Flames) that does 3 ticks, each for around 1350 damage. That means around 4000 damage total in 3 seconds. It has a 2.5 seconds cast and a pretty short cooldown and can take away half the health of a shard hide boar. Ideal for grinding Apexis shards.

Most Beholders (or floating eyes) are generally good too due to their Tongue lash that deals heavy damage and increases the effect of spells on the target, plus their spells are usually pretty nice too.

the beholders in blade edged mountains. they can debuff targets to take 50% extra magical damage :D otherwise... the big 4 armed sister things from near the dark portal. lvl 71-72 elites which can solo most horde :D lol

Probably the Homunculus in Kara cause it actually makes me feel usefull...

God I loved enslaving those annihlators. The best enslave ive ever done with 1500 point crits every couple hits. I had it tanking almost everything.
