Sion's death timer starts when he dies and not when Glory in Death ends.
If Sion lives longer than what his death timer lasts for, he will not revive until Glory in Death has ended. When it ends, he instantly revives. This may result in some odd interactions and bugs at times.
The effect that heals Sion back to full health at the start of Glory in Death cannot be modified by healing reduction and does not count towards the 'Damage Healed' statistic at the end of game lobby.
Glory in Death has a capped 60 seconds duration. If the player manages to survive for so long, Sion dies instantly, regardless of his current health.
The healing modifier during Glory in Death reduces all incoming healing, with the exception of healing from life steal and omnivamp; it does not matter if source of healing is Sion himself or an ally.
The health regeneration modifier during Glory in Death stacks additively with the modifiers of Boundless Vitality and Now and Forever, allowing Sion to have more than 0 health regeneration.
The fixed attack speed is achieved by lowering and increasing the maximum and minimum attack speed to 1.75, respectively.
This also means that it's unaffected by other attack speed modifiers for the duration, such as bonus attack speed or cripples.
However, Hail of Blades, which allows for the normal attack speed cap (3.0) to be surpassed, will also break this limit. This means that while it is active, Sion may exceed his 1.75 cap, but cannot fall below it.
When Hail of Blades ends, the attack speed cap will revert to 3.0 and not to 1.75, however Sion still can't fall below 1.75.
Some item passives do not persist through death and will be lost for the initial few seconds of Glory in Death.
The bonus on-hit damage granted by Glory in Death is unaffected by life steal.
However, it can be applied against structures that are not turrets.
The reduction of damage against structures includes Sion's basic attacks as well as on-hit effects that can be applied to structures, such as Demolish, Titanic Hydra and the magic damage based on AP conversion based on adaptive force.
It even includes true damage from sources such as Elixir of Sorcery and Bastionbreaker.
Sion, during Glory in Death, will not lose health while being carried by .
Glory in Death does not trigger on clones of Sion, such as with .
Glory in Death's untargetability from the stasis does not destroy in-flight projectiles.
Projectiles created while Sion is in the zombie form will still travel to him even after he dies.
Upon death, the current cooldowns of Sion's summoner spells are increased to 4 seconds. Afterwards, he is still unable to use them until he respawns.
However, it is possible for another lock-out effect to unlock them when their duration ends (excluding crowd control with the exception of stasis).
After Glory in Death ends, the corpse of Sion will retain unit collision despite being dead on the ground.
Buffs from jungle monsters that Sion acquired during Glory in Death will not be lost when the duration ends. (Crest of Cinders, Crest of Insight)
By surviving for the full duration of 60 seconds, Sion will have suffered floor(60/0.264)*(2.3 + (24.4-2.3)/17*(x-1))*(1+(floor (60/0.264)-1)/2*0.7)/1000 for 20 (based on level) in health costs.
Sion can also heal from spell vamp, although the stat is currently unobtainable and it would be also unusable during Glory in Death, since there would be no available abilities that would apply it.
Even though its visuals are present, Dark Harvest can never be gained from Sion under the effect of Glory in Death.
At the start of Glory in Death, Sion's mana drops to 0, but his mana regeneration will remain in effect.
