RNG should not be one of the main features inside the tower.
Floor 4, can spawn up to 4 Laikus at random and this should be taken out and instead spawn a fixed set of Laikus for tame(and only after taming all spawns the Bigger Laiku Boss) or completely remove them.
Bombs drop inside the tower can deal from 30% to 60 to 90% of bosses' HP and is too luck dependent and should be removed.
Talisman/Charm that enhances stats temporary should be removed as well.
Lastly, the outfits from securing the coveted spots should NOT have any stats as this provide players who secure the first week/month in the ladder a much great chance at winning the next one.
