This might be a bit...contentious. Which is why I'm giving it it's own thread. What about only allowing one spawner of each type? BUT, have each spawner be upgradeable with no max (or a max that is similar to if being 10K spawners in one). Likely upgradeable via prison tokens, but could be different (or a combo maybe of prison tokens and money). Using skeleton spawners as an example, could look something like this: Lvl 1: 5,000,000 and 50 tokens to buy. Spawns 4 skeletons. 25% loot rate Lvl 2: 75 tokens to upgrade. Spawns 8 skeletons. 25% loot rate Lvl 3: 95 tokens to upgrade. Spawns 16 skeletons. 25% loot rate Lvl 4: 120 tokens to upgrade. Spawns 25 skeletons. 25% loot rate Lvl 5: 145 tokens to upgrade. Spawns 40 skeletons. 25% loot rate etc, etc. Maybe every 10 upgrades adds 5% loot rate? Or, could be like the wyvern spawners, where there are multiple things you can upgrade within the one spawner. Could have one for spawn rate increase, one for drop rate increase, and one for spawn time decrease. Like I said, crazy spawner idea.
