Blackfathom Deeps was a breeze. They handled the naga and cultists, and I got every reward without slogging through those underwater caverns.
Rewards
Completing Blackfathom Deeps gives you valuable loot and progression boosts to your Warcraft Rumble account.
- Army Slot Upgrade: The first time you clear Blackfathom Deeps, you get an extra Army Slot to your leader’s army. This is huge – you can add another mini to your lineup (or give a mini a bonus level via the slot’s trait), effectively increasing your army’s power. More army slots mean more strategic flexibility and stronger teams, so this is a must have to serious players.
- Arc Energy (Arc): Every BFD run gives you Arc Energy, the rare currency to upgrade your minis’ rarity levels. A full clear yields hundreds of Arc (often +800 Arc Energy per run), so you can upgrade those Common minis to Uncommon, Rare and beyond. Warcraft Rumble Arc Energy is the lifeblood of mini progression and Blackfathom is one of the best farming sources for it in late game.
- Experience & Coins: You’ll also get XP for your account and minis by completing the dungeon, so you can increase your collection level and overall strength. If you already have all Army Slots unlocked, Blackfathom’s slot reward is converted into a big Coin reward instead. Coins are useful for buying troop upgrades and Daily G.R.I.D. offers – so either way you’re getting valuable resources.
- Loot Drops: While the main rewards are Arc and the Army Slot, any bonus drops (like random tomes, relics or mini tokens) you pick up during the dungeon are yours to keep. Every chest you capture or bonus objective you complete in those underwater maps can give you something extra. Our boosters will do a full clear so you won’t miss out on any hidden treasure along the way.
Each run through Warcraft Rumble Blackfathom Deeps is a stepping stone to faster progression, better minis and a stronger lineup overall. For players looking to get ahead in Warcraft Rumble, these rewards alone are worth every second saved.
