Renew is the primary Heal over Time (HoT) spell available to priests. It places a buff on the friendly target, healing them for a reasonable amount over 12 seconds. Multiple priests can place Renew on a single target, and a single priest can place Renew on multiple targets.
- The state (Holy ability) causes your direct heals to refresh the duration of your Renew on the target.
- (Holy passive) increases healing done by 15%, instantly heals the target for 15% of the total healing, and lowers the GCD of Renew to 1.0 second. This is the minimum GCD possible in the game, and this talent does not stack with haste.
- The Tier 5 four piece set bonus (level 70) increases the spell's duration by 3 seconds.
Initially, the healing from Renew ticks every 3 seconds, but haste will shorten the gap between haste ticks. By hitting 12.5% haste, Renew will gain a 5th tick over its uptime. Crossing this threshold will dramatically increase the healing done by Renew, and is often referred to the "renew haste softcap". By hitting 37.5% haste, a 6th tick will be added. It is possible to obtain extra ticks for every 25% of additional haste from that point on, but largely only via stacking multiple temporary haste buffs. Renew's speed, output and efficiency are increased by 25% for each tick added, allowing high-haste periods to transform the spell from a slow and often inefficient heal to a potent and extremely efficient spammable HoT. Renew cannot tick faster than every 1 sec.
Renew ticks can proc the Discipline passive , benefiting from the Discipline mastery , but will not proc the Holy mastery . However, Echo of Light is procced by the direct heal component granted by .
Renew is generally one of the most efficient healing options for a priest of any spec, and has the bonus of being instant cast. Its main down-side is its slow and relatively insubstantial healing. Using Renew pre-emptively or on non-critical targets is a good way to make the most of its efficient healing, as well as insuring them (in a small way) against incoming damage. However, Renew's efficiency and desirability is significantly determined by two main factors; the priest's haste, and their choice of specialization.
Holy priests generally get the most out of Renew, with two powerful bonuses that improve it substantially. makes Renew significantly more effective and efficient, adding an instant heal component and reducing Renew's global cooldown to 1 second, while the state causes all direct heals to refresh the duration of any Renew on the target. This allows a single Renew cast to last indefinitely, potentially providing limitless, extremely mana efficient (albeit very slow) healing. When tank healing, this aids Holy priests' mana efficiency and increases HPS with minimal effort. Holy priests can also cast Renew on multiple targets, and use cheap heals to maintain each buff.
Although lacking any specific bonuses, Renew is still a very useful and efficient heal for Discipline priests. Disc priests can make the most of Renew by timing their casts to coincide with their buffs. The buff allows Discipline priests' Renews to regularly benefit from an additional 14% haste, often adding an extra tick, without consuming the effect. Borrowed Time is particularly useful for enhancing Renew, since it has no cooldown and is procced regularly in the course of shielding, and when cast exclusively during Borrowed Time, Renew can become an even more effective and efficient option.
Although not the strongest of healers, Shadow priests can also benefit from Renew, thanks to . This makes Renew the only direct self-healing option available to Shadow priests without a cooldown. By self-casting Renew on cooldown, Shadow priests can maintain a substantial amount of self-healing without needing to drop .
Renew has advantages besides its efficiency. As an instant heal it can be useful in PvP when interrupts would prevent a cast-time heal. It can be cast while running and can be placed on multiple targets very quickly (especially with ). As an HoT it is also a useful way of insuring against silence effects and stuns. Renew can be used whenever incoming damage is slow enough to allow for its use, saving mana otherwise spent on more expensive heals. On the downside, as a magical buff, Renew has the disadvantage of being dispellable.
The concept of putting Renew up on as many targets as possible is known as "renew blanketing", which is a very potent form of healing, but also very tough on the manapool. A cheaper form of Renew blanketing is possible for Holy priests by applying the buff once and allowing to refresh the duration of the renew buff. This is far easier to maintain mana-wise, but lowers the amount of targets.
(Major) is an interesting option for priests. It increases Renew's healing by 33%, but reduces its base duration by 3 seconds. Although haste will generally mean that the duration is in practice reduced by less than 3 seconds, the result is the same: Renew becomes 33% faster, while its efficiency remains the same. This is generally a very useful and desirable improvement, making Renew a far more potent healing option. However, it competes for a Major glyph slot with alternatives that priests may find even more desirable.
