I believe this ought to spawn some sort of reward. It is impossible to overcome without the use of some consumables and that can be very, very draining to mid-level PCs that have very few of them.
I believe there should be a small recompense in the form of Purple Crystals and potions in a crate at the end, like it happens with some other invasions.
I saw this in IRC afterwards:
:: ( City Sending by Aberdenn Bannerman : Those who just aided against the war troll raiders: we`ve secured some of their supply before they could flee back to the swamps. Come to Muskroot`s and I`ll see it handed out. Locked in the Mist, we endure. ) ::
Oh, I must have missed that. Oh well, the niggling worm of poverty shall keep getting fed this day.
Just going to close this. Mistlocke invasions are usually overseen by a DM.
Invasions will sometimes be rewarding, and at other times will be exhausting. This is another element of randomness on EFU that ensures a certain level of chaos, uncertainty, and danger are a part of every adventure you undertake.
