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).
The new TLC for the Stego gave it three different battle modes that you change between using C on PC. Hardened is Damage Reduction, Heavy applies a slow to your opponent and Sharp ignores a good amount of armor. Finally, it is able to do an impale attack on an enemy when they reach a certain threshold and depending on the creature is is certain death.
Can confirm that the impale works on Rexes, though they can still bite you back given the proper angle. Also the Impale works when being carried by a Karkinos. Stegos are the new staple for fighting with a Karkinos. Let everyone know!
The new TLC update made these guys OP! Now they harvest tons of thatch, wood, and berries with their new plate forms! These guys are like tanks now! I tamed a lv 411 today, and it literally shreds though other dinos! By far I would tame a stego instead of a bronto, or a trike!
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.
