Enough for gear. For a Javazon using a Spirit Monarch, this will be 156 Strength as that is usually the highest Strength requirement for commonly used gear. If choosing to use another shield with lower Strength requirements, then just adjust your Strength to that value. This number always changes based on the gear you are using, though, so make sure to always double check the requirements for each piece of gear you have as well as how much Strength each piece will provide once equipped.
