I haven't tamed one yet, but here's two ideas how to do it safely

1: Common Trap

Outrunning a giga on a mountain is near impossible ehile shooting tranqs, thankfully us human beings aren't stupid. Gather 4-6 Metal dino gates and either ride a dino and place them ehile giga is standing or lure it inside (suggested use beartrap to hold it in) afterwards, just fire away!

2. Cliff Hang

My original plan was to use a Tapajara and hang on a cliff while shooting, so when topor run occurs, I can grapple on it or use Quetzal trick to KO the giga. Not sure if this idea works, but worth a go if you don't have metal gates.

TAMING GOOD FOR DINGLE PLAYER

Quetzal Kibble or raw prime meat are literally your only hope, along with over 100 narcotics or bio toxins. If you have a soothingbalm, it'll definitely take care of timespending.

Up so peeps can see.
