Number of Psychic attacks

[NikosWorkshop]

If I have a Tervigon in my army and I buy the additional two psychic powers, do I get to use all three of them? Also can I buy them and roll three powers in the rulebook power lists? It says in the Tyranid FAQ that the Tervigon got a mastery level of 1 but lots of people tend to take more psychic powers than one. This is confusing and I would be really happy if any one out there had this clarified. Thank you!

You can purchase additional powers, but since it is a level 1 psyker you can still only cast one per turn

When making the list, you can buy more powers.
When starting the game you may switch *all* of a models codex powers for rolls on BRB disciplines.
Terv is level 1, so can only cast 1 power a turn, more powers just gives it a better selection to choose from.

Read as higher chance of getting endurance/iron arm

So the Hive tyrant can generate two powers and choose to try to cast one of them every turn. The Swarmlord has four powers so I can switch out them for biomancy and get four but use two of the every turn?

Exactly, so the Swarmlord have a very good chance of getting Iron Arm for example out of the Biomancy table or tree or whatever you wanna call it.
A psyker`s mastery Level determines how many Powers he can use per turn (Mastery Level 2 psykers can use 2 Powers per turn since they have 2 Warp charges), but the Swarmlord have 4 psychic powers available which you can choose between freely depending on the tactical situation in a game.

Awesome, thanks! I have always rolled two for the swarmlord and one for the tyrant on the biomancy board but now I can take much more advantage of the charts! Thank you!

That should help yes. Imagine the Swarmlord with Iron Arm and Warp Speed from the Biomancy table: S9 T9 I9 and 7 attacks (provided you get a D3 on both Powers) with Fleet and Eternal Warrior xD
The large number of psykers we can bring to a game sure is one of the Tyranids` strong sides, and you`re welcome.
