Frequently Asked Questions (FAQ)
Based on community discussions, here are answers to the most common questions players have right now.
1. Is the "Luck" Gamepass worth it?
Community Verdict: Mixed/No. Many players report that the Luck Gamepass only affects Player XP (leveling up your character) and not the drop rates for rare monsters or eggs. "It only affects the exp in the user not pet xD" "600% luck my " Advice: Save your Robux unless the developers clarify exactly what "Luck" boosts.
2. Which is better: Flarecrest or Glazadon?
Verdict: It depends on your playstyle. Flarecrest: Higher DPS (Damage Per Second) but lower Health. Best for killing bosses quickly if you have a tank. Glazadon: Balanced stats with decent HP. Better for general farming where you need survivability. Note: For Endless Spire Floor 50, both are better than Mountusk because they don't take the 200% extra damage from the Earth-counter boss.
3. How do I get the "Turkey" monster?
The Turkey was an event monster. Currently, you can only get it if: You have leftover Turkey Eggs from the Thanksgiving event. You participate in an "Admin Abuse" event where admins might spawn special eggs.
4. Why can't I pick up boss drops?
There is a known bug with Glazadon's Pull ability. If you use a skill that pulls the boss too far from its spawn point or into a wall, the drops might glitch out or become unreachable. Fix: Try to fight bosses in open areas and avoid using displacement skills right before the boss dies.
