Sharpened plate mode is fantastic at getting biotoxin from red mushrooms, don't even need to be close enough to endanger yourself. Also gets great weight reduction on berries and all the Abberation mushrooms except aggeravic.
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).
Very useful in PvP to soak turrets because if it’s abilty to protect the rider and high HP. Back into turrets as it’s tail takes reduced damage, beware of tek turrets as the splash dmg can still get you. Also it’s helpful to bring a few sweet veggie cakes so the stegosaurus can regain some health. (Up if you found this helpful)
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.
One of the best dinos to use for the new shadow mane prowl and ferox cull because of the ability to not be dismounted when hit. One of these guys with a good saddle plus a group of reapers you can easily solo alpha!
