Here i shared a model of spreedsheet that can help with that:
Any Fireball, Heroism and Luck Scroll should be probably a requirement because these will increase the total guild score for the rewards and leaderboard and make the climb easier in higher levels.
If one or more players are willing to spend enough gems to have all Forge Scrolls to max out the weapon, all Shop Tiers plus Last Tier two extra times and then all 25 scrolls from all Floors, they could play first and map out nearly all rooms and still have sigils left by the end of Floor 25.
