I would like a 200 QP requirement, because it originally needed a quest to be completed. This is not too high of a requirement, due to the fact that the majority of players who will be high enough combat to kill corp should already have 170+ qp because they probably already have barrows gloves.
You need to make sure you list the specific stats and effects that the NON-modified 2008 divine/ely will have, otherwise there will be many people who might look at the effects they have from rs3, which is different from the ones in 2008.
This is the 2008 effects of the spirit shields.
Divine, quoted from the Knowledge Base in 2008:
"30% - or as much as if possible if 30% is more than your current amount of Prayer points - of any damage you take is removed. Half of this 30% is deducted from your Prayer instead, while the other half is ignored completely".
*note: This effect works 100% of the time, assuming you have the prayer points.
*note: This DOES NOT remove half of the original damage from prayer. It removes half of what is absorbed from the prayer.
E.g. if a player hits 40, they will instead be hit a 28. 12 damage was absorbed by the divine, so the player with divine will lose
only
6 prayer points.
With a 75 prayer requirement to wield in the first place, the effect on prayer is negligible.
I would suggest reducing the effectiveness of the spirit shield to work 75% of the time instead AND remove twice as much prayer as before. (in the above example, hitting a '40' would hit 28 instead and reduce pray by 12.)
Now for Elysian, the knowledge base stated:
"70% chance of reducing the damage you receive by 25%"
I think this chance should simply be reduced to 50%.
Spectral/Arcane have no special effects like divine/ely, but they are best in slot for magic attack (arcane) and magic defence (spectral). I don't mind this tbh, they are fine.
