This came up due to something the other night.

1: Assume Flora Colossus (2x2 base) stands atop just a Bucket of Water (a special object that makes a single square of water terrain). Does he count as occupying water terrain, or does his entire base have to occupy water terrain to trigger the extra healing from Drink Deep, Sapling?

DRINK DEEP, SAPLING: Flora Colossus may heal past its starting lines but can't heal except by this trait. At the end of your turn, you may roll a d6. 5-6: Heal 1 click. If it occupies water terrain, heal 2 clicks instead.

And (though I know it's not any longer a valid resource) from the Final 2014 Players Guide:

Special terrain (printed orange squares) that require a character to
occupy the square, require that the entire base must be occupying the
terrain.

The reason I'm asking is simple. I remember that some years ago, multibased characters who only partially occupied the Lava Squares on Muspelheim (which reads "At the end of each turn, deal 1 unavoidable damage to each character occupying a Lava Square") were ruled to not take damage from the Lava Squares.

Am I missing or misremembering something here? Most importantly, will only a single square's occupation of terrain count as being in that terrain?

Please clarify. Thank you.

From the Rulebook under Multi-base characters p33

A multi-base character occupies all of the squares its base occupies and is adjacent to each square adjacent to the squares its base occupies.

So if one of the squares that the flora colossus base occupies is water then it should heal 2 clicks.

Also, there now is wording to specifically mean what the old PG entry used to reference. Look at Mangog- If they intended the Flora to need to be completely in water terrain instead of just one square, it would be worded like that.
