I decided to open the tomb (Unseeing Eye quest) and fight the Shade Lich for fun. It made me realize that my party composition might not work very well in the long run. My previous BG2 run, my main character was a Sorcerer and I had Imoen+Aierie that are 2 other mages, Anomen cleric caster/tank, Keldorn and Jaheira which is an other fighter/caster. Overall, I often built my parties around a sorcerer or mage so I wanted to do different this time around and add a few of the classes/kits I was curious about and wanted to try. So my party is currently
1- Darkmoon Monk
3- Wizard Slayer
I intended on getting the sword that reduces THAC0 (I forget its name but it's one of the best 2h in the game) on my Wizard slayer, dispell magic with Keldorn and have the Wizard Slayer beat onto casters (and then whatever is left) debilitating the enemies (Monk and archer being extra DPS, F/T to handle traps and backstab + DPS and Shaman as support). I avoided using Dispell magic as often as possible last time I played BG2 because I had a ton of buffs on my party from having so many spell casters so I only used it if I had absolutely no choice. Now I realized that it can't deal with certain spells or spell setup (Improved Mantle + Globe of Invulnerability), Mantle blocks all of my physical attacks (including dispel arrows) as the best weapon I have is a +4 scimetar and rest of my weapons are mostly +3 and some +2 and I think that Globe of Invulnerability absorbs the dispell magic spells so I can't dispell the Mantle.
I still managed to kill the Lich by waiting out some of his buffs, spreading out and having a few of the weak shaman spirits aggro it occasionally when they would decide to walk up to him or if I could lure the Lich close enough to them. However, the Lich killed 3 of my party members with a spell I forget the name (instant death). Although I was able to rez them with the Shaman afterwards, it will not be a viable strategy (or will get tedious) in the long run.
-So my question is:
Are there tricks or items my party member can get in order to deal with the strong Caster defenses or is my party going to be very bad each time I face one of those? Although I enjoy the flexibility of the Shaman to be like a Sorcerer and not have to waste spells slots on spells just in case, the class feels underwhelming to me so far. I've used the Shaman Dance here and there for fun but it never turns out to be truly needed or good for real. Its class unique spells are kind of bad (the 1st level one is rather weak, 2nd level I've never really used it... deals 1d3 dmg AOE and 20% chance to snare, it's awful. The 3rd level is like a very weak fireball. The 4th level is alright to dispell a mind condition and the 5th one is ok but it's basically resurrect which I could also have on a cleric but maybe later in the game). The weapons and THAC0 is still too weak to be truly viable for damage and the armor is weak. Overall, if I must add a mage to dispell strong Caster defenses, I might switch the Shaman out for Aerie for a Cleric and Mage dispells.
