Varla Stones in The Elder Scrolls IV: Oblivion are rare magical items primarily used to recharge all enchanted weapons in your inventory at once. When you use a Varla Stone, it fully restores the charges of your enchanted weapons but is consumed (destroyed) in the process

What to do with Varla Stones:

• Recharge enchanted weapons: Use them to fully recharge all your magical weapons simultaneously, which is especially useful in mid to late game when your weapons have high charge capacities

• Save for later: It’s advised to save Varla Stones for when you have high-level enchanted weapons, as using them on low-level gear is inefficient since the stone restores the same amount regardless of the charge level

• Sell for gold: Early in the game, if you find Varla Stones before encountering many enchanted weapons, selling them can provide a good amount of gold (each worth about 1000 gold)

• Collect from Ayleid ruins: Varla Stones are found mainly in Ayleid ruins, often in cages or on high pedestals. They are rare and valuable, so gather them whenever you find them

Additional notes:

• Varla Stones are crafted from meteoric glass and are enchanted shards capable of restoring magical energy to enchanted items

• Unlike regular soul gems, Varla Stones recharge all enchanted weapons in your inventory at once but are destroyed upon use

• There are flawed versions of Varla Stones that act like reusable soul gems but with weaker recharge power and do not get destroyed

In summary, keep Varla Stones for recharging your enchanted weapons when needed, especially in the late game, but selling them early on is also a viable option if you need gold. They are rare and valuable, so use them wisely
