Hey there! I just wanted to share some knowledge with you how to build ET offlane in different cases. Read description under situational items and make a desicion what to buy. It's necessary to analyze enemy pick and build to make a desicion what to get.

I recommend to analyze lane matchup. U must know how aggresive can u play from 1st minute. From first wave try to hit as much creeps (ally, enemy) as possible to get some exp advantage against lane matchup. In 90% cases you can start playing aggresive from lvl 3 because there is strong boost of your damage from Astral Spirit (2nd ability).

When "Grabbing" damage with Astral spirit always try to use first on support and after it on core, cause core-hero is always in lane trying last hit some creeps:)
Also try to stack damage from neutral creeps spots. It will significanlty increase damage and will allow you to kill enemy heroes in pair with your support faster.

I hope it will help you to have more wins with such amazing hero as ELDER TITAN. Have fun :)
Thanks!
