Cryptbloom

Cryptbloom is a 3,000 gold Magic Penetration item in League of Legends for mages who want some team utility with their damage: 75 Ability Power, 30% Magic Penetration and 20 Ability Haste in patch 26.22. Its Life from Death passive releases a healing nova from the corpse of any champion you damaged within 3 seconds of their death.

What does Life from Death do?

It turns kills into healing for your team. When an enemy champion dies after taking damage from you in the last 3 seconds, a nova spreads out from where they fell and heals allies caught in it.

Riot’s data text leaves out the heal amount and the nova’s size, so the in-game tooltip is the place to read the exact numbers. The trigger is clear, though. You need to have damaged the champion within those 3 seconds, and you don’t need the kill yourself. An assist counts, which matters a lot for mages who poke from the back line and rarely land the last hit.

How often does it fire? In a team fight, potentially several times in a row, since every enemy death you had a hand in spreads another nova. In a long poke war with no deaths, it does nothing at all, and the item is just 75 Ability Power, 30% penetration and 20 haste.

Is Cryptbloom worth the gold?

On stats alone it comes to 83%: 2,500 gold of value for 3,000 gold, a 500 gold shortfall before the passive and the penetration count.

To be fair, the gap exists because only two of the three stats have a price. 75 Ability Power at 20 gold per point is 1,500 gold, and 20 Ability Haste at 50 gold per point is 1,000 gold. The 30% Magic Penetration gets no value in the table, as no basic item sells it, and that’s the stat people actually buy the item for. Real talk: against a tank with a resistance item, that penetration alone is worth more than the missing 500 gold.

Cryptbloom or Void Staff?

Same 3,000 gold price, same kind of penetration. The choice comes up every game a mage faces resistance. Void Staff has more of it (40% against 30%) and more Ability Power (95 against 75), which makes it the pure damage pick. Cryptbloom trades that for 20 Ability Haste and the healing nova.

So the rule is simple enough. Carry mage who needs every point of damage? Void Staff. Mage who casts a lot and fights with the team, or a utility caster whose kills happen in group fights? Cryptbloom, and the haste alone can be worth the smaller penetration number if your damage spells have long cooldowns.

What does it build from?

An unusual recipe: Blighting Jewel for 1,100 gold plus two copies of Fiendish Codex at 850 gold each, and then only 200 gold to combine (one of the cheapest combine steps among legendary items). Fiendish Codex first gives haste and a little damage early, Blighting Jewel first gives penetration when the enemy already has resistance.

Nothing builds out of it.

Why does the history start in 2014?

The item ID belonged to Dervish Blade, an old Magic Resist item, which is why the full table above begins at patch 4.3. Patch 14.1 renamed that slot to Cryptbloom and raised the cost to 2,850 gold. Since then:

• Patch 14.19: Ability Power 70 → 60.
• Patch 25.08: Ability Haste 15 → 20.
• Patch 25.10: cost 2,850 → 3,000 gold, Ability Power 60 → 75.
• Patches 14.2 and 14.21 changed only the effect text.

Put simply, Riot nerfed the damage once, then gave most of it back along with more haste and a higher price. The LoL items database tracks the same history for every other item in the shop, Dervish Blade included.

Who should build Cryptbloom?

Mages who fight with their team and cast often: battle mages, control mages with long cooldowns, and AP champions who count assists more than kills. Several deaths in a row means several novas. Honestly, it’s also the better pick when you’re already behind, since the haste and healing help a team that can’t simply out-damage the enemy.

Solo-lane assassins and one-shot mages lose less from skipping it. Thing is, they want the bigger 40% number from Void Staff, and they rarely stand next to allies when the kill happens. Is your team fight a pile of allies around one target? Then Cryptbloom pays off on every death, and the only question left is whether to buy it third or fourth.
