Supporting Earth Shaker will often move between lanes and usually will be bottom and middle lane. Players will often go with tri-lane tactic with shaker on their team as they can get kills with shaker spamming fissure and blocking paths of enemy heroes. Remember if you want to block heroes with fissure, do not click on the hero, instead click slightly behind the enemy hero to inflict damage,stun and also block his escape path. Then ally heroes can gank the enemy hero. always choose to gank the hero with lowest HP and click on enemy heroes to check their magic stick charges in order to get a sure kill. Smoke of deceit will come into use when shaker is moving between mid lanes so as not to alert the enemy hero in middle. If you do this right and timing is good you will have gold and level advantages compared to 3 enemy heroes that are taming tri-lane. Save up for Boots of speed and buy some smoke of deceit in between. Then save up for dagger so as to be of full assist during battles and also to catch enemy heroes from a distance.
