If you don’t want to run around gathering fiber and wood to quickly build a base last moment before the Allosaurus pack nearby spots you, if you want to tame Argies quickly and effectively, if you want to take out raptor packs quickly, you will need a stegosaurus.
With the new TLC the stego can easily become a must-tame early game dino for many players. It has 3 stances when ridden you can change between pressing C (crouch):
Heavy plate, boosting thatch gather rates and applying a heavy slow on hit targets.
Sharp plate, boosting berry gathering and attacks penetrate armour (useful for PvP).
Hardened plate, boosting wood gather and halves damage taken.
For combat, heavy plate is great for effectively rooting enemy and wild dinos in place, whilst hardened plate is to tank everything that comes at you. Sharpened plate shines together with allies that can slow and/or tank whilst you focus on dealing good dmg.
The alternate attack of the stego can impale creatures up to the size of roughly a parasaur, dealing damage based on attack damage. In order to do so the target must have a certain amount of health left, which is highlighted with the crosshair turning red when looking at the target (unsure how it is shown without crosshairs).
These big guys are not to be underestimated. They have a slow speed, but don't let this fool you. Once tamed, they can gather insane amounts of wood, berries, and thatch. I suggest taming these as soon as possible. Use upgrade points on health, melee dmg, movement speed, and stamina. Hope this helped.
The stegosaurus is great for wood gathering if you need a bunch and don’t have a lot of time because of their massive weight capacity. Even though it’s a pretty slow tame it is great for gathering resources in abundance.
I have a stegosaurus called Strega and she’s a GOD, can kill five giant beavers in a few swings, has very high health, doses decent damage, and helped me and my only tribe mate, my dad to tame our first giant beaver.
