Weapon of Destiny: Stat Growth & First Item
Check Weapon of Destiny stat growth per takedown in Patch 26.21. Compare two-stat and three-stat items, then choose a first Legendary for your champion.
In Patch 26.21, 
Weapon of Destiny makes your first Legendary item grow with champion takedowns. Choose stats your champion can use. Assassins can consider Serpent's Fang; mages can compare Shadowflame and Void Staff. Fix mana or haste shortages before committing to a damage-only first item.
Stat growth per takedown: 20 attributes checked
In 26.21, each qualifying takedown splits a 200-gold growth budget equally among the item’s N upgradeable stats. Gain per stat = growth coefficient × 200 ÷ 1000 ÷ N. The budget is shared, not awarded separately to every stat. You must damage the champion within 3 seconds before their death. The chosen item cannot be sold.

Percentage gains are percentage points: 40% penetration +1.5 points becomes 41.5%. Values are rounded to two decimals; the game may round its display. Eighteen attributes have growth parameters; the two regeneration entries have none listed and are excluded from N here. Only existing stats grow; item passives are not upgraded.
With two upgradeable stats, Serpent’s Fang gains about 3 AD and 3.5 lethality; Shadowflame gains 5 AP and 2.5 flat magic penetration; Void Staff gains 5 AP and 1.5 penetration points. Three-stat Infinity Edge gains about 2 AD, 1.67 critical-chance points and 0.4 critical-damage points. Concentrated growth still needs useful stats.
Choose the stats you need
Serpent's Fang offers attack damage and lethality for physical burst. Its shield reduction also matters against shield-heavy teams. If your damage relies on sustained attacks, do not abandon attack speed, critical chance or sustain just to grow lethality.
Consider Shadowflame for finishing low-health targets and Void Staff when enemies build magic resistance. Neither solves a mana or ability-haste shortage. A mage who keeps running dry needs resources to stay in fights.
Fewer stats do not make an automatic winner
Remove options that spend heavily on stats you barely use. A mage with no mana problems need not buy a mana item specifically for this Augment. Conversely, a frequent caster should not drop all haste to concentrate on power and penetration.
Growth needs takedowns. Delaying your first completed item, or buying one that leaves you unable to fight, slows the payoff. Compare the components and immediate fighting strength alongside later scaling.
What to buy afterward
After a damage-only first item, check sustain and survival for your second purchase. If the same crowd-control combo keeps killing you, consider defense. If the first item already solved mana, spend later gold on damage or protection.
FAQ
Do assists grow Weapon of Destiny?
Yes. The live description specifies champion takedowns, which include assists. Join fights you can contribute to; risking death to secure the final hit is unnecessary.
Must a mage buy Void Staff first?
No. Void Staff fits a need for percentage magic penetration. Mana, haste and surviving long enough for another spell rotation can be more urgent.
Can I copy a 100% penetration endgame build?
The final stats depend on the item, takedowns and patch. That result is not guaranteed every game. First buy something that lets your champion contribute, then plan around its growth.
