A level 50 Snorlax and my lv60 Roserade easily smashed them. Snorlax soaked damage while I hid'n'sniped, and Froslass went down quickly after being crippled with Toxic and being repeatedly hit with Shadow Ball and Crunch. Vector's Snorlax went down shortly after Froslass was beaten, but Glalie was no problem; Toxic Stalling always wins me boss fights. Fight lasted less then four minutes practically.

Icicle Cave is... weird. It's pitch dark, and it's got the smallest hallways I've ever seen in this game. The fights so far aren't that hard to solo with Roserade, the only hiccup I find is if they throw Screech debuff on me, no amount of maintained Leech Seeding and Giga Draining helps with that. Buttttt the server is going down so I doubt I'll finish that quest before then.

BTW, just like to make note that Roserade cannot reliably defeat them without proper team support like Snorlax can provide. However, like earlier today, Roserade CAN beat them with a fellow grass type Venusaur with just luck, not with the excuse of "just strategize better". Froslass & Glalie, due to their AI, did not spam Ice Beam and Ice Shard as nearly much as they should've on the fifth attempt at fighting them in which we defeated them. Thanks to that we were lucky to survive just long enough to deal enough damage to kill them. Normally they'd just kill us with 4-6 hits easily within two to three turns due to their boosted PP. AKA, with proper AI, we'd have no chance.

o.o yah  we were lucky lol
