I’ve been thinking of how strong wraithpact was and how underrated am’s shard is.
Put the two together and you get the effect of the old wraithpact! Moreover offlane am loves building vlads early.
Add in a mage slayer and AM literally takes no magic damage, and whomever he’s hitting will have their total magic damage output reduced by 65%, and their physical output by 30% which is ridiculous.
Build is of course game dependent and I would only pick offlane am into a magic heavy lineup, but when it works oh boy does it work.
Build is ooc->boots/vlads->treads->wraith pact->shard->mageslayer-> situational survival or lockdown item (heart,manta,abyssal,skadi)
Could also build glimmer cape instead of mageslayer if you need a reliable escape item early on.
