Thunder Belt

DefenseFinished item1,820g

Hybrid defense item converting your own defense stats into a periodic AoE true-damage nuke and hard slow.

Stats

HP: +600; 1820
Physical DEF: +15; 80
Magic DEF: +15; 48
Movement Speed: +20%; 65%

Each bar is scaled against the highest value of that stat on any item in the game — the faint number at the end of the track is that maximum.

Passives and actives

Unique PassiveThunderbolt
Every 4 seconds, the next Basic Attack deals 50 (+100% Extra Physical Defense) (+100% Extra Magic Defense) extra True Damage to the target and enemies around them, and briefly slows them by 99%. Hybrid Defense permanently increases by 1 each time the attack hits an enemy hero. (This effect is reduced to 50% for Marksmen and Mages)

When to build it

Not a counter-item; buy on tanks/fighters who stack both Physical and Magic Defense, since Thunderbolt scales its true damage off your extra defense and applies a near-total slow every 4 seconds. Best as a frontline engage tool, weaker on Marksmen/Mages who only get half effect.
