Swamp Cave is great when taming one of these guys, no Ghillie is required just bug repellent. Make sure you clear the area first because swamp cave is a bit difficult and bring extra sets of scuba tanks. Creatures can get up to level 200-400 so be prepared and watch out for arthropluras
Make 1 foundation and put 8 walls on it making a 2 high box without a lid, drop the spider into this funnel like trap, when you see it's legs show through the trap from the outside look at them directly and you can feed it, you do not need bug repellent for this
So, biggest thing no one tells you on here. If you only have repellant and no ghille, put it on and go at them from the SIDE!! Not head on, not directly behind. The side. Never aggros on you that way. From the back and front even with repellant it aggroed 3x each before i tried it this way.
