since the primal weaponry has already been discussed im not going to adress stats or details of them in here. note: i think they should be added untradeable, with a very high repair cost).
currently im busy with the comp cape grind ( wanna finish it before comp cape (t) comes). one of the biggest parts of comp cape is 120 dung. as im writing this im at 106 dung and already bored to death. its a very tideous grind with nothing to work towards beside the comp cape requirement. i think adding a game option for your points would fix this.
the gamble option woud cost you 1 million dungeoneering points and give you a chance for the following:
1/40 very rare :primal weapons
1/25 rare: primal armour ( i would place it between grae and torva), primal recharge token?.
1/10 common: choatic recharge token, dungeoneering lamp(s) (other stuff which you can use for dung weaponry).
and some stuff as a addition to fill up.
this gamble option would only be available for 99 dung and above.
i think adding this system would give a more meaningfull grind to dung and something to do with your dung point(s). i hope to hear your opinions about this method.
btw: dont comment primal will be easy obtainable. to be certain of one primal weapon you will need 40 million points, thats 5 to 10k laps ;).
