Wall - one point wonder, or worth investing?

[Newbie1234]

Wall is great in certain situations.

From my experiences, the AI tends to just avoid the wall and really only attacks it as a last last last resort. I have a couple of points invested in it, and it's something like 1800 health and 30 defense, which has been more than enough so far. You don't want too little health, or else multiple hex attacks (eg. Phoenix, Cerberus, etc.) might kill it accidentally.
