Plain and basic, lethality is a fact in League of Legends that grants flat armor penetration utilizing a formula. Back in 2013 nevertheless, it was part of a mastery tree, and in this post we will go through what lethality has been to the League of Legends community.

In 2011, Lethality was part of the tier 5 Offense mastery tree. Any champ that dealt physical damage might benefit from Lethality, which at that time increased crucial strike damage by 3.33/ 6.66/ 10%. Lethality was altered the next year, and now its result per rank was an extra 10% critical strike damage. Players were required to have 12 points in offense and 4 points in Deadliness in order to have the mastery. By this time, champs that had Infinity Edge as part of their builds gained from the passive. Infinity Edge’s passive stacked lethality for a 260% total vital strike damage.

You may have looked at that number and questioned the peace of mind of the designers, but do not stress, Lethality was nerfed in 2013. Well, more like fine-tuned. The crucial strike damage of ranged champions could increase by 2.5/ 5% whereas melee champions got a 5/10% benefit. Players needed to have 12 points in offense in order for Lethality to be a part of their attack damage proficiency constructs.

Just by browsing “Lethality League of Legends” you will discover plenty of people either posting videos of their junglers eliminating enemy squishies in one shot, or of players grumbling about how broken lethality is. And, with the best construct, it type of was.

So Riot Games eliminated it, for the most part.

Lethality became a figure that represents armor penetration. With what little math knowledge I have, the finest way to describe lethality is as follows:

FLAT ARMOR PENETRATION = LETHALITY x (0.6 +0.4 xlevel ÷ 18).

It’s rather confusing, but at the end of the day, it is a type of armor penetration. The more lethality you have, the more damage your champ offers. Some products that increase lethality, in case you are interested, are Draktharr’s Shadowcarver, Duskblade, Eclipse, Syzygy, Edge of Night, Prowler’s Claw, Sanguine Blade, Snake’s Fang, Serrated Dirk, The Collector, Umbral Glaive and the infamous Youmuu’s Ghostblade.

Lethality was, for a long period of time, an extremely strong statistic to have and champs like Pyke and Aphelios integrate it in their kits now. Gamers are seeing a return in lethality, even if it is not in their proficiency tree. Regarding whether pros will integrate it in the competitive scene once again, that remains to be seen.
