There is a bad news(may be a good news for someone), I just noticed that we can not get leo often recently, coz we may get all other events also while burying bones like MoM and strange box(mostly) , drunken dwarf, swarm, evil chiken, highwayman, captain, sandwich girl, genie etc even camo(we only get zombie, shade and leo b4 april while burying bones, thats y ppl got full zombie so easy). So leo event becomes a lil uncommon nowadays, but u will still get him for random, just do ur normal combat training and bury any bones they droped, whatever they r, whatever small or big bones. Thats a bad news to me, coz I got only 1 or 2 per day now its really hard to achieve my goal. And yes, Leo does give u a replacement item if u lost one. Hope that helps.
