Divine prod
A person who uses a Divine Spirit shield's advantage that annoys other players versing someone wielding one because there nubs who cant hit on them.

The Divine spirit shield was released on 15 September 2008 along with Summer's end. It is currently the most expensive shield in the game. It requires 75 Defence and 75 Prayer to wield. The shield is made by attaching a Divine sigil to a Blessed spirit shield. To do this, players need 90 Prayer and 85 Smithing.

The Knowledge Base states that the Divine spirit shield comes with a special bonus, "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."
For example, if a foe using Dharok's armour and other damage-boosting methods/equipment would normally hit a 600 on a person wearing this shield, the damage would be reduced to 600 - 0.7=420, and 1/2(60-42)=9 points would be deducted from this person's prayer. The damage reduced by this shield is therefore limited to 2 times one's current Prayer points, e.g. a player with 3 Prayer points can have 60 life points reduced from any attack.
