I consider myself a pretty good BG2 player, for someone who plays on Core difficulty. I have all the difficulty-upgrade Tactics components installed, all the Improved Five, etc., etc. Imp Ilasera was easy, I didn't even reload once on Gromnir or Sendai, and Abazigal was no big deal once I realized that the purple dragon somehow darts away before my timestopped horrid wiltings hit him. Balthazar dies so fast I wasn't sure what happened.
Even the first part of the final battle is doable, though tough. I rush Zombie Balthazar (I have the Longer Road mod installed, which adds Irenicus to your party, and he steals a soul from one of the Five, turning one of them into a zombie--no changes really, just the name) and kill him in one round.
Fine.
Ilasera is ethereal already and running to some weird place and planning to unload some Dispell/Miscast arrows on poor Edwin. Irenicus and Edwin have Ruby Rayed Abazigal, and Mel pops out. Irenicus Breaches Abazigal so Sarevok, Korgan, Viconia, and PC can wail on him. He starts to run around the entire map like a pansy, but hopefully he dies soon. Maybe another Breach is needed after he Prot:MW, but whatever. Ilasera is dispatched next, if I'm lucky enough for her to not go ethereal after Badly Injured.
Fine.
Sendai is brought out by True Sight and Breached sometime during the previous two. Everybody wails on her, she twists her retarded onyx ring and forces everyone to chase her around the map for like ten rounds. Finally, hopefully she dies. But not before Mel starts doing the most annoying thing in the entire fight: Gate.
She gates in four enemies at a time, and there is no way I can prevent all of them, including the Cambion archers, from hitting Edwin or Irenicus. If I divert my attention to taking them down, Yaga Shura will wtfpwn my characters. I have to keep taking Viconia out to Greater Restoration everybody. I just realized I could Harm Yaga Shura, so I'll try that next battle, but so far, it takes forever to finally kill him.
Now Mel goes nuts. With the Five out, she starts Gating like CRAZY. She doesn't even melee. She just Gates and puts up Divine Shield/Absolute Immunity. And then Gates. I can't take all of them out. The Succubi all charm Sarevok, the Balors all Vorpal hit Edwin, and the Cambions are just raining arrows on everybody. I simply do not have a Ruby Ray handy at all times to bust on Mel because my mages are always using up their round doing something else, like using Rod of Ressurection on a 30HP Korgan or something. The only thing that can possibly save me is turning my Kensai->Thief into the Ravager, but even that doesn't help because between Gates, Mel RUNS AROUND THE ENTIRE MAP. What the hell. While I'm chasing her, the archers just rape me. And if I kill off her summons, she Gates more in the meantime. This is just a lose-lose situation. I've even tried to TS+IA+delayed blast fireball etc., but what does she do? Dimension door before the TS runs out. And then proceed to Gate in more homos.
Next time I try this, I'm going to cheese the hell out of this. I'm going to use every piece of Userunfriendly's cheese guide I can, because this calls for it. I'll Mindflayer circlet somebody useful, like Yaga Shura, I'll Project Image summon an army of Planetars, whatever. This is just silly.
P.S. Anyone else feel that Tactics actually makes SOA harder than TOB, because TOB doesn't have any enemies that close the debuffing loop and force you to Chain Contingency Ruby Rays?
