Ok I've seen several tips like run but that doesn't help your dinos or base :_: . So here's my simple steps process to lure it away from your base. 1st hop in water and swim down if shallow run under rocks and stuff. 2nd find unneighborly neighbors. Run by their house and place a tamed dodo or easy animal adjacent to the wall. Wait for the giga to wreck m. Remember stay far away. And take your reward.
