General

I am no expert at Dojo, but I can place if I do it.

Keep in mind that you should have Elemental Reset on at all times except Manon and Lilynouch.
For Manon/Griffey, Telecast is the key, but you should be doing it for everything on and after Manon if you don't lag too bad. You can't really expect to tank it if you have a low range.
I usually never use Infinity on bosses that can dispel. So time accordingly.
Spend some money and get decent HB.
If you're just looking to finish, use power buffs at the rest spots.

stay on the edge of ur cl range, see an attack? telly cast back right after cl. telly right back in and cl. they easy way to do that is to cl>tele back>cl>tele in>cl

@ justsofly If u dont mind doing less DPS to pap, u can try to pin pap in 1 corner and then stand all the way back spamming flame wheel. This way pap will never do stun/dispel/iframe attacks.

Was going to say something, then I remembered this was a mage
Er...all I can say....er....Telecast...err....Avoid, what they all said^
Normally if you want a Arans opinion though buff-wise
Use the buffs that are necessary don't use the ones that aren't (going for gloves = anything that doesn't improve your range/Helps you survive = unnecessary)
The 1minutes+ buffs
I would usually save them till the end(Being a Aran I have no use for invincibility so...)
Power > Lyka
Bamboo Rain > Mu Gong
and I usually buy the 1minute +60ATT Power Gloves before the last round.(Although I don't know if there's a option for M.ATT)
Sorry if I was of no help o.o ...I am a Aran after all.

What I do for Pap is:
Debuffed? : Recast Meditation+Booster, if it sleeps: rebuff everything.
Slow and use Ice Demon+Flame Gear(if you have it).
Always try to keep Oz's Flame+Elquines(if you have it) summoned.
Tele-cast when needed.
And pretty much just spam Chain Lightning+Glacier Chain.
I'm also experimenting with the Dojo buffs to see which string of buffs would benefit me the most.
This is what I've been using: 30Attack, 60Attack, 1Attack Speed, 2.5kDef, 30Attack, 4kDef, 60Attack.
I still haven't finished Dojo yet.. I keep dying at Lyka.

Edit:
Changed up my buff line up to: 60Attack, 30Attack, 4k Def, 10k HP, 60Attack, 10k HP, 4k Def.

@jh92 You can completely avoid Lyka attacking if he spawns more towards the left half of the screen. I find that if you corner him to the left and attack from a certain distance (distance cap with Illusion) he'll just stop attacking allowing you to just spam. This should work with I/Ls as well seeing as how CL has a larger range.

IMO the most annoying boss is Pap...because you can't really avoid getting debuffed, plus he has iframes.

P.S. debuffing is an issue for me...since evans have a lot of buffs + the decent skills I have and the slow cast delay =/

The only bosses that give me some trouble are griffey (dispell, strong to lightening), Dodo (those fish bones ), and lyka (sed + 4-5k dmg from its attack). You'll need 2-3x your range TS to solo in a decent amount of time.

Leviathan is easy, but the tot bosses are hard because they attack more frequently. Dodo, avoid the fish bone attack by timing your jumps. Lily, has a very long attack range(but u can avoid its ground pound by jumping at the right time). Lyka, use hero's will when u can, and avoid the pillar attack by moving away from the markings on the floor

Pap will ge easier as you improve you're equips. The worse bosses are leviatan, the blue horse boss from tot, and the seducing boss from tot (those ones drain a lot of mp and hp and can be annoying to try to spam). Mugong himself is pretty easy though but the last stage before him in ranked mode without buffs is painful....

Infinity before you head into pap, make sure that you know how to telecast backwards and forwards to avoid anything and everything.
