So I've tried all pk-based minigames, and they all have one thing in common: a lack of obstacles (Castlewars has most obstacles, but is mostly a large field with a river). So for a long time I've been considering a minigame that's more congested. A minigame that has the same rules as the Fight Pits (in other words...survival).

THIS IS A SAFE MINIGAME!!!

Requirements for minigame:

Shadow of the Storm quest
100 coins (for every time entering portal)

To start: Enter the Evil portal (if first time speak with Evil Dave first)

After talking to Evil Dave, you'll then see a portal nearby. Enter to start minigame (though you can enter any time you feel like, just bring 100gp)

You'll start off at a tower with a portal where you came from, however the rest of the arena is blocked off by a sinister wall, which lowers upon the start of the minigame. The arena consists of agility obstacles and bridges (kinda like the Agility Arena in Brimhaven, except the towers aren't properly aligned). Upon entering, you'll be given a Forefit Tablet (it's pretty much a Teleport to Edgeville tablet, as it teleports you west of the bank).

You'll start at the top floor, but you can go to lower floors, as they have less agility obstacles.

The bottom is where you'll land if you fail an obstacle. The entire arena is within a rift.

Periodically, Evil Dave will summon various creatures (Similar to the Fight pits in TzHaar City). They vary from the following:

level 21 Toxic imps
level 40 Colossal Poison Spider Hatchling
level 70 Colossal Poison Spider Adult
level 82 Smog Lessers
level 92 Smog greaters
level 100 Kalphite soldiers
level 200 Elite Kalphite soldiers
level 300 Dust Storm (only one, can fling others away)

NOTE: All of them poison

Rune Scimitar (rare)
Level 2 Clue Scroll (somewhat common)
Coins (10gp-2500gp, most common drop)

Nothing (Half the time)

Dust Storm Drops
