What is this summon used for? he is a "recharger" to your mana, but why an ES need to be recharged? Tell me something that I "cant see" on that useless summon....(also lich 30% of your exp)
40-54 or so the ES can be levelled as a nuker.
-Nuke until out of mana
-Summon Boxer
-Fight with boxer for awhile while recharging until you have drained the boxer's mana... then send the boxer away
-Nuke until out of mana
-Repeat
The Boxer is also quite useful when you have a smaller mixed party and you are attempting to hold a tougher area.
Boxer's recharges mean the ES can hold the Boxer up longer with heals.
I never playe an ES (or any other light elf for that matter), but from my experience with warlock's kat the cat, it can be used for some "perpetual healing". While you can't do a huge spike heal like bishops, you can heal / battle heal pretty much non-stop (and body to mind / group heal if you eventually run low on hp) so for many levels you can be an effective healer (presuming you have a real buffer with ya).
Your hp healed per cast will be low, but your hp healed per hour will be huge because of your insane mp pool.
I've used boxer in dungeons, where I'd have trouble with mp using merrow. But the 30% xp leech is a turn off.
You could just use merrow and summon boxer when you need recharge, but I find that annoying, so I didn't do that.
This summon is low level, it can be used from 25 or so till around 50 when you still can nuke. I have heard, not confirmed my self, that you can recharge the pet and have it recharge you and create infinite mp for yourself. Probably takes a long time though. it's power is lower then that of the merrow and uses more xp, however if you need mp consistently for something you could use it.
