I picked this up from martjin's presentation, Ibut I agree it goes too far
"Solution: OGNL dynamic expressions" - i wouldnt mention ognl because we do

Indeed, this is something that has changed since Martjin's talk. I'll update
it accordingly

makes sense
instead of strength.add(new attributemodifier() might be better to do

I think the attribute modifier is pretty obvious to understand, and there's
already an example with AttributeModifier when talking about Behaviors. But
I like your code too, it makes more obvious there's a lot more you can do
with a behavior than modifying an attribute. So there's pros and cons for
both IMO, I'll see if I can show the two (one when talking about behaviors,
one in the example).
Thanks again for your valuable input,
Xavier
