Leaf is an excellent Rune Word for a lower level Sorceress. The Warmth bonus really helps keep the Sorceress casting her spells. Both runes are very easily acquired (the Ral Rune is given as part of a reward for an Act V quest, while both are common drops from The Countess), and the low requirement level allows lucky Sorceresses to have an easy time until mid-Nightmare or even Hell. When combined with a Staff which innately already gives a bonus to the Warmth Skill, this staff potentially generates a total of +9 to Warmth which is very helpful for early game Sorceresses where mana depletion is a constant issue. However, it has the downside of being a staff rune word, which precludes equipping a Shield with this weapon.
A 2-socket staff required for crafting Leaf with good skill bonuses can be easily acquired from Drognan in Act II on Normal difficulty. Make sure to roll a map with Lut Gholein gate at northeast (near Drognan), so you can quickly exit and enter town in order to reroll vendor items. However, staves with bonuses to higher level skills, such as Meteor or Fire Mastery cannot be obtained from vendor and have to be found.

- This is very similar to the unique staff The Salamander, but if made in a carefully chosen staff it will have much higher skill bonuses.
