Hey guys! Bolas do not WORK! Use bear traps instead! Up this to save a life!

So I was on ragnarok and saw a 140 megalania so o thought ooooooooo gimme dat so I got my cross bow and 113 tranquil arrows and shot one and only one.......THAT THINGS FASTER THAAN SANIC BUDDY BOI THERES NO OUTRUNNING DAT THING

Spiders cant climb walls in this game but this fat lazy looking reptile can, whats next? Argys that cant fly and penguins that will fly faster than wyverns XD

Knocked a level 5 feamale out with about 10 tranq arrows was not prepared for the speed of torpidity loss bring lots of narcotics

This thing can climb on everything. Its better in climbing then the thylacoleo and a good mount to have

To easily tame it, bring a few bolas, lots toxic arrows with your crossbow or bow, lots of meat, also tons of biotoxin (which you can easily get by killing the shiny jellyfish thingy around the shores). Once you fínd a Megalania, use your bola and shoot ton of toxìc arrows at it, in between use your bola again so it doesn’t escape. When it’s knocked out (I’m sure you know the rest) feed it meat and biotoxin to control its torpor. WOLA! You’ve just tamed a MEGALANIA!!

It doesn't seem to like leaving the cave, it'll sit at the entrance while you shoot it in day light

In the new valentines update they changed the torpor decrease by half.
