Ark Survival Evolved - SOLO Gamma Manticore Boss Fight

Singleplayer Gamma Manticore with 5 Rex & a Fire Wyvern.
Tips:
1. Don't use Wyverns. Their Torpidity is too low. Learned it the hard way.
2. Stimulants don't work against Manticore venom on tames. Only works on you.
3. Rex is the goto dino. If transfers are allowed, Theri, Allo & even Carno can take Gamma down easily.
4. Manticore is easy, does puny damage. Real threat comes from Deathworms & much later the Rock Elementals. 5 Rex as I found out is more than enough.
5. Stats for your dinos should be 10k-20k health & pump everything else in to melee.

My Server Stats:
Increased Taming, harvesting & imprint bonus stats.

I use slomo/gamma & ghost(when I get glitch stuck) as my only admin commands.

Very rarely, I would spawn items(Manticore skin) or dinos(Giga, Alpha Wyvern since they are rare & I won't waste unnecessary time on search & kill dinos for a chance to spawn them)

I've also transferred my veteran dinos(Anky/Beaver/Doed/Argy & Rex Eggs) from the Island using Transmitter which have made my SE journey a breeze
