there are 3 additional puzzle at vaha's head the mini boss before the final boss. climb on to the very top of the structure and u will find 2 more puzzle. the first one is matching pattern with blocks.

as u will see there are some floating blocks, those indicate the pattern of the same type of blocks. the floating pattern will change and its different each time its completed.

and match the floating pattern with the 3 pattern on top, only the pattern match the floating pattern will be you solution. u can figure out the 4th one automatically.

2nd puzzle

standing at the orb where u activated the puzzle here is the walkthrough( im not a great drawer)

star is the beginning position, if u follow it correctly the pillar will aim beams at the orb.

sorry i dont have a screenshot for 3rd puzzle but its pretty straight forard.  there will be 2 platform a control pannel ( the sphere/orb) and a moveing platform for u to stand on.  one person need to stand on the movable platform while one person rotate from 2 platform and stand on it ( light indicate it will be the one working) and 3rd person interact with the control panel. its pretty ez just know that its buggy sometimes need to ineteract with the orb alot.

after finish all the puzzle and beat the final boss once, u will get a journel from black spirit that will need u to interact or do puzzle again for more knowledge
