Oracle

Nerif the Oracle is a ranged intelligence hero who alters the fate of allies and enemies. Best known by his ultimate, False Promise, Oracle can temporarily render allies impervious from healing and harm by this unreliable but potentially highly-rewarding prophecy. Oracle can also deal large amounts of damage and healing since his skillset has such a versatile range of combinations. One instance is that of greatly damaging enemies with Purifying Flames and then preventing these healing flames from regenerating HP by the purge effect of Fortune's End. Another way involves rendering enemies' weapons useless by the judgement of Fate's Edict, or using the same ability to provide magic resistance to your allies. Knowledge of Oracle's skills is key to use him at his full potential; one mistake can potentially seal the fate of your allies.

 * Considering most heroes' base magic resistance of 25% and no other sources of it, it takes 6.14 seconds for the heal of to cancel the damage, which is 67.5/135/202.5/270 health. After that, it effectively heals 31.5/63/94.5/126 health. Since the spell heals in intervals, the healing outpaces the damage starting from the 7th second.
 * A powerful healing combination is to cast Oracle's and  with Winter Wyvern's  on a target ally or oneself. The result will give full physical and magical damage immunity, as well as healing for 64 + 6% of the target's maximum health per second at maximum level for 4 seconds from Cold Embrace and 44 health per second for 5 seconds thereafter from Purifying Flames. The total heal is, therefore, 476 + 24% of the target's maximum health. Using this combination on an ally effected by  will result in a heal of 952 + 48% of the target's maximum health.

 * has a slow projectile, while ' effect is instant. This means you can cast first, and before the projectile hits, use . This will prevent the target from healing at all from.
 * Before a fight is about to happen, especially when pushing or defending your base, keep casting on your carry. Since it has a short cooldown, you can ensure they will start the fight with at least 2 instances of healing (the healing is stackable).
 * removes most negative buffs from the target, like does. Try to save it for when your target gets stunned.
