Do you think it that players who have auras have an advantage in dangerous PvP over those who don't? As far as I know I know, all combat auras except those specifically marked as not working in PvP (sharpshooter knockout, runic accuracy and friends in need) can in fact be utilized in PvP that is dangerous.
Take a look at this list of benefits: Poison Purge is a healing agent that can keep your body continuously for 68 seconds or 168s if you went to Zammy GWD. Invigorate - restores spec faster. Inspiration - restores spec faster. Vampirism - 5 percent healing from the damage, is stacked with soul split
Penance - 20% prayer repairs damage taken. It can cancel either the effect of Smite or Divine's prayer drain. Berserker - +10% att and str (similar to the effects of an additional potion), -50% defence, stacks with potions. For 1 def pures defence reduction does nothing. Dark Magic - chance of slightly more damage from mage. Ancestor spirits – an additional vengeance effect may be possible (not confirmed). Aegis: 10% reduction in damage. It stacks with soak, divine and ely.
Although I don't normally post anything about Runescape, I wanted to share my experiences in RS as an individual player or pker. I noticed that pkers bot more frequently than normal players.
I have extensive in Pking. I observed that a lot of users botched actual evidence even though they were training at extremely suspicious levels. (99 str 20att, for instance 90-99 on level 40-60 accounts and 90-99 in skill on level 40-60). With this large number of botters who also are Pkers, it appears that there is an obvious trend.
