OxygenOT is an Open PVP world. Players can attack each other outside protection zones once they reach the protection level.

PvP damage is also reduced by level. See the player damage page for those tiers. Connection and rates stay on server info.

A Red Skull Remover can clear a red skull and frags. It has a 24-hour cooldown and cannot be used during PVP-E.

Normal PVP uses separate daily, weekly, and monthly frag counters.

• 5 hours to remove 1 daily frag
• 2 days to remove 1 weekly frag
• 5 days to remove 1 monthly frag
• Killing a player whose level is less than half of yours grants 3 frags instead of 1
• PVP-E uses a separate frag system. It does not share these daily, weekly, or monthly counters

PvP Experience Weekend lets you gain experience from killing players. It runs from Saturday after Global Save until Sunday Global Save.

• No EXP from same IP — players on the same IP do not gain experience from killing each other
• Diminishing returns — each repeated kill of the same player reduces EXP by 50%. Resets every server save
• Level range — you only gain EXP from players within 70%–200% of your level. Example: level 100 gains EXP from targets between 70 and 200
• Damage share — experience is proportional to the damage you deal
• Death refund — XP lost on death is subtracted from your PVP-E gained EXP. At the 30B cap, dying frees room so you can fight and gain EXP again
• Separate frag system — PVP-E frags are isolated from the normal daily, weekly, and monthly system
• Red skull reset — any red skull is cleared when PVP-E starts, and again when it ends (Sunday Global Save)
