Other minis and map mechanics

Gold spawns faster than usual in Grenka’s gold mines. In normal, the gold spawn timer is 22 seconds, and in Heroic, it is 14 seconds. When a gold mine reaches 3 gold, Grenka will summon three Harpies with Trinket Collectors talent to mine it. If you kill the Harpies but do not mine the gold, they respawn after 15 seconds.

Grenka Bloodscreech:

  • 5200 health
  • 9 aggro range
  • Cleave: 180 Physical damage, 1.8 seconds attack speed, 2.5 range, 120 degrees arc, 4 radius

General strategy

Grenka is a battle over gold. If you let Harpies spawn and mine, Grenka can be difficult, but if you get to mine the gold, your army will snowball rapidly.

There are already three gold nuggets on the bottom right mine, so you need to get there and kill the incoming Harpies right away. With an aoe mini, you should be able to kill them before they have a chance to mine and your own Kobold Miner can get to the gold.

There are two gold nuggets on the top left mine, and it can be hard to reach that in time. However, if you deploy a S.A.F.E. Pilot when a mine gets its third gold nugget, the Pilot will land just in time to kill the spawning Harpies. If you have a Dark Iron Miner in your opening hand, you can also mine the gold safely before Harpies spawn.

After stabilizing the gold mines, attack the Tower and push towards Grenka from there.
