Elven Elder's Guide

Elders can be considered to be the intermediate class between Human Bishops and Prophets, mixing the elements of healing powers (and mana recharging abilities), offensive abilities, and buffs. As with all Elves, Elders have high natural Wit (useful for faster healing and buffing), but also suffer from low Intelligence (lower magical attack abilities; a weaker output damage)

Equipment/PlayStyle
The Elder receives both Robe Mastery (physical defense per point) and the Mage Light Armor Mastery (not to be confused with the Light Armor Mastery of Fighters, the Mage's version adds physical defense per point, along with increasing attack speed, mana regeneration and casting speed exactly like the Robe's passive skills Magician's Movement, Mana Recovery, and Spellcraft). The benefit of using Robes is the addition inherit mana increase found on robes. Light Armors provide additional defense whilst having all the benefits of wearing a robe jacket / pants combination.

The main playstyle of Elders should be caster, and therefore wearing mage weapons and robes.

Any mage weapon that has Acumen SA is most likely the best option, since it increases the Elders already abnormally high cast speed even more. Health SA weapons are also popular option for Elders that like to PvP a lot since it increases their max HP, allowing them to take more hits. Matk plays small role in Elders spells, spells that require decent matk weapon to be effective are Trance/Block Windwalk/Wind Shackle/Mana Burn/Might of Heaven/Erase.

Armor sets there was numerous choices but of because the armor that increases cast speed/mp regen are the best choice. Blue Wolf robes set is most typical armor as it offers boost in max MP/MP regen/Cast Speed. Higher grade robes, if you can afford them, such as Dark Crystal robes increase Cast Speed the most thus making it very popular choice for PvP healers, for PvE Majestic Robes set is perhaps better since it increases MP Regen a lot, it does also increase cast speed and has anti-stun property thus making it also good choice for PvP healers.

Of course, there are many different playing styles that fall in between, for reasons varying from personal preference to Adena issues. Don't let what is given here limit your possibilities.
