and for the first time we have some optional abyssal gems, i think more strongly they can be related to xestris'  advice to build a "defensive barrier made from true elements found within the Tower"

EDIT: found an error, in the yhilin foundation, the 'key point' grant +1 yhilin tower, not +2 EDIT2: another error, in the 'takkan tower 1' page the fight with the reality leech grant +1 takkan tower, not yhilin tower
