Staff of the Great Sage

Slot none; Aura strong evocation and transmutation; CL 30th; Weight 5 lbs.

DESCRIPTION

This long wooden staff was crafted by a powerful wizard over 2,000 years ago from the limb of the silvery-white Eushon tree. Carved with sigils and runes of power, this powerful +5 holy adamantine shod quarterstaff can be used to smite opponents, and contains an enormous array of spells and powers. Unlike a normal staff, the staff of the great sage holds only 25 charges, but regains charges at the rate of 1 charge per day, as long as 1 charge remains. It cannot be recharged normally. While some of its powers use charges, others do not. A staff of the great sage does not lose its powers if it runs out of charges. 

LEGENDARY POWERS

Basic Abilities legendary power (8/day), legendary surge (+1d20; concentration and caster level checks), mythic bond.
Advanced Abilities eternal bond (arcane spellcaster only), foe-biter, metamagician, powerful (x3), returning, undetectable, unstoppable 
   strike, upgradable.

POWERS

If 1 charge is expended (a free action), the staff deals double damage (x3 on a critical hit) for 1 round. 

The staff of the great sage also possesses a number of spell-like powers. The following powers do not use charges:

The following powers drain 1 charge per usage:

These powers drain 2 charges per usage:

These powers drain 3 charges per usage:

The wielder of a staff of the great sage gains and a +5 luck bonus to AC and on saving throws. The wielder also gains spell resistance 30. If this is willingly lowered, however, the staff can also be used to absorb arcane spell energy directed at its wielder, as a rod of absorption does. Unlike the rod, this staff converts spell levels into charges rather than retaining them as spell energy usable by a spellcaster. If the staff absorbs enough spell levels to exceed its limit of 25 charges, it explodes as if a retributive strike had been performed (see below). Unlike a staff of magi, the wielder knows how many spell levels are cast at him, as it communicate this knowledge as a rod of absorption does.

The staff of the great sage can be broken for a retributive strike. Such an act must be purposeful and declared by the wielder. All charges in the staff are released in a 30-foot spread. All within 10 feet of the broken staff take hit points of damage equal to 10 times the number of charges in the staff, those between 11 feet and 20 feet away take points equal to 8 times the number of charges, and those 21 feet to 30 feet distant take 6 times the number of charges. A DC 23 Reflex save reduces damage by half.

The character breaking the staff has a 50% chance (01—50 on d%) of traveling to another plane of existence, but if he does not (51—100), the explosive release of spell energy destroys him (no saving throw). 

Unlike other staves used in a retributive strike, the staff of the great sage is never completely destroyed. The staff regenerates itself at the rate of 1 hit point per month, until it is fully regenerated. Once it is fully regenerated, it remains without charges until it is recharged through spell absorption.

DESTRUCTION

The staff of the great sage can only be destroyed if it is broken in a retributive strike, doused in unholy water, and cast into the flames of the Elemental Plane of Fire
