Hello there. Generally, I'd say offensive builds are the way to go in this game. By that I mean, putting all your stat points into ATK/MTK, and making sure all enemies get defeated as fast as possible before your low defensive stats get you killed. To make up for that, give Lace the Scroll of Healing Wind (Gloomy Forest), and the Spellcaster's Hat (Beach Cave) and Beautiful/Elegant Kimono (Silky's house in Gloomy Forest), so he can always heal your group afterwards without you having to spend too much cash on healing items. Doing the dungeons is the fastest way to farm EXP, so given how far you are in the game, I'd say, give the Adventurer an axe, like the Seductor (the lumberjacks in Logwood can randomly drop that one) or the Anchroar (random drop from Duiro's left boss chest). As for Wulfrick, give him either the Big Fisting Fist (an NPC in the Beach cave near the exit gives it to you), or the Thunderos (3rd Fire Dungeon floor, random drop from Flameron's left boss chest). And since you only got the Fire Dungeon for now, give Lace a Crying Scepter from Anubu's shop, and give him a water spell item.
On Pine Island, there is one item that boosts your EXP gain, so before you start farming, make sure you get that one!
If you already rescued Wizzy from the Fire Dungeon, craft some Ruby Rings at his shop in Shiptown for more ATK, get the Biker Jacket from the skunk in the Shiptown bar for more ATK, and try to farm the rat boss in the rat cave for his entire armor set for, you guessed it, more ATK. (If the Fire Dungeon is still too hard for you atm, you can also use the rat boss to farm for now. Or since Fucko can't join you on Western Island, just do the enemies on Pine island for now.) Wulfrick's Spiked Collar is by far the best accessory here. If you wanna be extra risky, you can also give Lace the Tor's Covenant (Gloomy Forest) for more MTK, but it means sacrificing a spell slot, essentially. As for Fucko, it's basically the same as for Adventurer and Wulfrick for now. On Pine Island you can get some new weapons for him, but for now, ATK build all the way!
