Drill bush before Q: start Rootcaller from your own brush whenever you can, then remember the follow can stop at max auto range so you choose the spacing instead of autopiloting into melee .
After 6, play around Daisy as the body — shield Daisy when nobody else can make contact, shield the ally already crossing the line, and use Q plus Daisy as peel first when the enemy dives your carry .
Stop playing bot lane like poke-enchanter attrition; Ivern is strongest when Triggerseed can actually stay attached long enough to pop, and recent data supports that his better games come from one early off-lane turn where brush, Q, and Daisy all arrive together rather than from forcing random face-up trades
Start with whoever will actually stay in contact long enough for the slow and detonation to matter. In lane that is often your ADC if they are already stepping forward, not just the closest ally on screen. After 6, Daisy is usually the default carrier when nobody else can cross safely, because she gives you a body that can walk in without risking your own position. If the enemy has already committed onto your carry, put E on the threatened target or on Daisy for peel, then use Q to keep the diver in range of the pop. The bad habit is spending E early for chip when nothing can hold them there.
Ivern cannot attack or be attacked by non-epic monsters. Ivern can create magical groves on jungle camps which grow over time. When the grove is fully grown, Ivern may free the monsters to receive gold and experience.
Ivern conjures a vine, dealing damage and rooting enemy targets hit. Ivern's allies can dash to the rooted target.
In brush, Ivern and his nearby allies attacks deal bonus magic damage. Ivern can activate this ability to create a patch of brush.
Ivern places a shield on an ally which explodes after a short duration slowing and damaging enemies. The shield refreshes if it hits no enemies.
Ivern summons his Sentinel friend Daisy to fight with him. Re-cast command Daisy to attack or move.
