Long-term pet grinding can seriously impact your mental health and enjoyment of OSRS. Here's how to stay sane:
Expect to go 2-3x drop rate. 86.5% of players will get the pet within 2,000 attempts.
Decide your maximum attempts before starting. Stick to it to avoid sunken cost fallacy.
Use external calculators to see your current luck percentile. Going dry is normal.
Burnout is real. Set weekly limits and engage in other OSRS activities.
Pet Penance Queen is the most expensive, requiring an average of 100M+ GP and 400-600 hours. Each high gamble costs ~100k GP with a 1/1000 drop rate, making it both the rarest and costliest pet in OSRS.
It depends on your goals. If you value prestige and collection completion, yes. If you prioritize efficiency and profit, focus on Olmlet or skip expensive pets entirely. Never grind expensive pets for practical benefits - they're purely cosmetic.
Bloodhound costs 50-80M GP on average, requiring hundreds of Master Clue completions. You'll need supplies for clue steps, plus the initial investment in Elite clue completions to access Master clues.
Yes, TzRek-Zuk offers the best balance of prestige and reasonable time investment among expensive pets. At 1/100 drop rate (1/75 on task), expect 100-150 completions costing 20-40M GP total.
Set a hard limit before starting. Most experts suggest quitting at 3-4x drop rate unless you're enjoying the process. Use probability calculators to understand your current luck percentile.
Olmlet is the only profitable expensive pet grind. Chambers of Xeric generates significant profit through unique drops while hunting the pet, often 200M+ profit during the grind.
