Here are my thoughts: lvl 2- reduced defence: Will lower the defence of OSRS Gold whoever is atacking you by 10%, however your defence will lower by 5%. Lvl 5- lower strength: Will diminish the potency of whoever is attacking you by 10%, but their defence is raised by 5 percent. Lvl 7- Lower Attack: Will diminish the atack of whoever is attacking you by 10 percent, but their defence is significantly increased by 5 percent. Lvl 10- Kill defence: Will lower the defence of whoever is attacking you by 20 percent, but your defence is reduced by 10%.
Lvl 13- kill strength: Will lower the potency of whoever is attacking you by 20 percent, but their defence is raised by 10%. Lvl 16- kill atack: will lower the strike of whoever is atacking you by 20%, but their defence is raised by 10%. Lvl 19-grave robbing: If killing somebody, they shed one item and that item appears in your inventory or, if you do not have space, it appears on the floor. When killed, you maintain 1 less item. Lvl 22- rotting flesh: whoever attacks you becomes diseased for 1 or two every 30 seconds. Your defence slowly decreases
lvl 25- blood rob: whoever attacks you has their health regeneration decreased by half. Your health regeneration is lowered by 1/4. Lvl 25- rust: rots turns and food any bandages, rations, etc. to vampire dust. Lvl 27-rigor mortis: anyone who strikes you cannot block and the damage against them is doubled. Your harm is decreased by half.
Lvl 30-cramps: anybody who attacks you has their power lowered by half and will oftentimes be knocked-down. Your wellbeing is reduced by half. Lvl 33- obliviated: anyone who attacks you has their attack lowered by half an hour. Their weapons will often be unequipped automatically. You cannot block. Lvl 37- Dissonance: you produce three spirits which are lvl 67 who ignore armor and stats. Their maximum hit is 25. One additional spirit ignores by rs 07 power leveling half of your armor and attacks you.These spirits cannot be atacked.
