Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
ALl depends on the game if you have super cc and caster against then swap thornmail for force of nature but in my opinion when they are hiting you 6 seconds with your thornmail it is enouth.If you have some problems with kills in late/impossible/ wiap tiamat for sword of occult.
to the blodthirsters i think lifesteal on tryndamare is bool**** cause lower you are hiher crit chance you have .i think this is more team oriented trynda - last game i hada kyle in team and we just rocked them cause i got most kills they focused at me i got low on my ulty and when it was going to end kyle just put his u on me i ended another hero kart did me on angel but i survived!yea
