General

 * Stealing Intelligence from enemy heroes for 80 seconds (140 with the talent) can make a big difference between enemy heroes and give you a high advantage.
 * At level 7 (which is where can be maxed out) with   to Intelligence, 2x ,   (or  because it have same intelligence) and 8-10 intelligence steal from enemy hero or   (to   for great crowd control) its nearly impossible to lose your mana.


 * This is your main damaging ability later on in the game. As an Intelligence carry, you directly benefit from items which increase your Intelligence due to the increase in your right-click damage, mana pool and resultant damage.
 * Need more tips.


 * With you can save yourself or allied heroes from  and  if timed correctly. In addition, you can save allied heroes from potentially lethal abilities such as  and.
 * Similarly, it can also be used to dodge projectiles. It is important to time it so that the projectiles connect while imprisoned, since the spell does not disjoint projectiles.
 * When an ally is affected by a damage over time effec, Astral Imprisonment can be used on them to negate some of the damage, which can potentially end up saving the ally. Especially against long lasting debuffs, like and, a lot of damage can be avoided, since it can be cast twice before the debuffs expire.
 * On the other end, Astral Imprisonment cast on enemies can heavily backfire. Just like how it can save allies from spells and damage, it can also do the same for enemies if timed badly, so communication with the team is important to prevent wasting spells.


 * Assuming Essence Aura is at its max level, Outworld Devourer needs 1000/1200/1400/1600 mana in order to not run dry of his mana pool.


 * This ability is best used as a finisher; after acquiring enough stolen Intelligence in a teamfight or gank, can be used to snuff out any remaining enemy heroes, especially escaping invisible heroes like,  and
 * Keep in mind that heroes which gain Intelligence at extremely high rates such as, and  will often take minimal if not zero damage from this ability. As such, it's best to refrain from using this ability against these heroes unless you're significantly ahead in Intelligence and certain it can finish them off.
