+Adds an option to let you easily multiply the amount of spawns you're getting, updating live.
+
+## Softlocks
+This mod is known to cause softlocks. The game handles "kill all enemies" objectives in half a dozen
+different ways for example, and not all of them interact with this properly. When something
+softlocks, SQing and disabling the mod, completing the objective without it, and then re-enabling
+it, should let you progress further.
+
+These softlocks are not considered bugs, they're just the cost of doing business. The only bugs are
+ones that break your save, and prevent progressing even after disabling the mod. This is not to say
+that spawns which softlock won't be blacklisted at some point, just that I won't spend time actively
+hunting them all down.
