Troll Invasion

Completed the easy version of it which has 20 levels. Was extremely easy as you'd guess it would be, especially since there's a potion in the corner that for each wave you can use 5 times and it heals all your health, prayer and restores all stats back to full, but it will disappear if you let the dynamite guy run into it (Just range him once and he explodes).

The only real damage you attain is due to you being silly and not moving for either the mage's roots spell or the ranger who throws boulders.

All in all pretty fun and neat update in my opinion, I haven't had the chance to try the harder version of it yet, but seen a youtube video of 'Cliff' on the final wave on it and it seems pretty easy as well.

Edit: Oh and just to add to this, making it an event even this month wouldn't be so bad because people can redo Troll Invasion multiple times a month, just not able to gain experience the second time around per month. Maybe during this first month, people who have already completed it could redo it in the harder version if they haven't done so already, and those that haven't tried it out yet could go get their experience for this first month.
