Quagmirrian + Pulsing Globule Dehydrates distracts the champ equipped with Pulsing Globule, rendering it unable to use Toss. Then it blows up. Cleanse could screw it up though.
Tried that, Makorov, but your enemy has two full turns to react unhindered, not worth it What is worth it: Shock Pomfret + Tidemasters Bandoleer Boghopper Mentor + Feeding Frenzy (10 extra damage from boost), also works with PHS, but only 6 extra damage
Fire Volatility (Sixul if FF) + Swamp Worts + Poison Cloud (or Cone, etc.) Essentially, make use of Poison Cloud to trigger Volatility by turning it into Fire damage. Keep in mind that making it Fire damage will keep things like Poison Charge from helping though (though Fire Charge should, if you're running a split).
I just imagined a scene where the swamp tries to kill sixul with poison and he just turns everything to ashes.
Tome of Arcanis on any wizard makes spot metamorphosis(so firks are a huge target now for that equip ) My combo is more Tortun but it still counts as FS! SL/FS Mangleshell, x2 Thunder, x2 Nora Drain, x2 Corsair. Basically if the cogs get to spinning in the bg, your opponent never makes any nora due to Thunder(- 10 nora on hit of opponent champ) x2, I take pillage on my Mangleshell, plus Tariff, and Nora Drains to be a Cobra Spitter.
off the top of my head... sixul's flame siphon + nora shield sixul's flame siphon + mucker firk mindcaller + draksar psion - backlash causes 2 extra damage to soultapped champions AND it stacks mucker + backfire/backfire boon - people almost always try to finish them off with a spell.
