Now, I'm sure a decent amount of people don't really know about the "TradeNExp" warp (located in the right corner in the spawn). And yeah, Pioneer+ ranks can silk touch spawners and with SF you can get spawners and fix 'em up, but this warp is a good place to start out for new(ish) players. Two of the four rooms have spawners in them (one with Vindicator and another with Blaze; they have two spawners each [from what i can tell]). Now, my suggestions here, are possibly filling up the two...
