My new favourite thing is packing crates with different combinations of ordnance and lobbing them at the bad guys (especially fun vs large groups of enemies).
Here's one cocktail that took out five enemies outside the Goblin camp and mortally wounded several more:
• 1 Void Bulb
• 1 Bomb
• 1 Smokepowder Satchel
• 1 Alchemist's Fire
• 4 Bottles rum
Shake well before serving.
Anyone else found any effective combos?
