I have Valygar in my party and i had to go to the sphere in the Slums.
I almost killed Lavok, but then he told all about what happened to him and about i must get the hearth (i think) of a devil. I went out of Sphere and arrived to some kind of hell. There are Lea'liyl and Tanar'ra and I can't kill them. What is the easiest way to do it?
Plus, I meet Tolgerias in the Sphere, who also isn't easy to kill. I have a quest to do about seeing Tolgerias in Goverment District, so do I have to see him in Sphere?

Oh Yes! This Is A Very Tricky Fight! To Get The Heart Of The Demon Is HARD!!! He Uses That "DeathGaze" And Really Annoys Me! What I Did, Was Get The Person With The Best Save Vs. Death (Or it May be Spells, You May Have To Clarify That) And Send Him Forward. When He Saves Vs. DeathGaze, Bring In The Rest Of Your Group Into Melee (The Rest Should Be Way Back Out Of Range Of The Spell)

Hope This Helps!

I prefer sending some summoned serveants (jaheiras fire elementals, Skelletons (warriors), spiders...). And then hiting them with the tanks

Tolgerias can be beaten with standard anti-mage tactics:
1.) Try to hit him with every wand and fast spell you have available
BEFORE he builds up his defenses (Mages don't have a lot of hp)
2.) Memorize some Breach or SpellThrust
3.) Try out Miscast Magic on him
4.) Try to whack him with a tool that does extra damage (i.e. Flail of Ages, Flame tongue, Hammer of the Thunderbolts, Gesen Bow - You probably have one of them - not the Gesen I think)
5.) walk in sight - walk out of sight and wait for protections to wear off
6.) Use the Ring of the Ram <evil grin>

And yes Tolgerias is the Wizard you were supposed to meet. He would have send you after Valgyar as a bounty hunter to procure his body
so he could enter the sphere.

Faceman, he can't use the Ring of Ram, since you get that out of Tolgerias dead body [img]smile.gif[/img]

You can solve the puzzle and kill tolegrias before going outside to get the heart.

Also for some mages who like to throw up a contingency, watch to see if protection from magic weapons come up. Weapons with added elemental dmg should still pierce thru. IF you have a wand of monster summoning, use it. Normally these critters don't have magical attacks. There's been quite a few times I wait and then cast a few ogres to bash the magical-defensive mage to pulp. Those monster summonings come in handy when you least expect em to. I don't suggest using the wands of monster summoning against big time npcs who have an innate resistance to non magical weapons. Plain mages aren't the case and the critters eat up the mage's death spells. I didn't use spells for Tolgerias. Having the staff of magi, I whacked em silly to watch em conteingency and then send in the pets. I also made him waste his true sights early and threw one up on my own. Pets did the beat down and took the death hits. Proceed to melee em and there shouldn't be a problem if you had fodder.

For the Demon, my traps didn't work when I lured him to them using my bounty hunter. I had to have Minsc use the flail of ages on him after Aerie maintained enough aggro ( EQ talk)...finally cleared out the whole area to have extra hearts left over as souveniers. I had the boots of speed at this time. Got Aerie to pull the demon from the top left-side. She kept the thing on her while she used the ring of Gaxx. I pulled to the entrance way to the sphere and there fought em with Minsc primarily. During the fight, I switched the ring to have Minsc use it. Also haste is rather important too.

The demon DOES see thru invis AND casts enough dmg to hurt, really hurt. My bounty hunter couldn't solo em for sure at lvl 16.

You can pickpocket Tolgerias for the Ring when you meet him first. That way you get two rings, which makes fighting mages a lot easier.
