It's a guessable password + guessable ruleset. You've introduced far less entropy than you've imagined. If you want to have protection against attacks and use your technique, you have to come up with a ruleset you (1) don't see in the documentation (2) that's computationally unreasonable.

For instance, combine multiple languages. Strawberry Octopus Sundae, which is pretty memorable, can become FragolaOctopusEisbecher combining Italian, English and German. And with that we just went O(N^3) where N is dictionary size (actually more than that because you've got a wide choice of latin scripted language).

That gives you far more protection then say sTr4b33ry+0ct0pu5!5und43. You aren't fooling a GeForce RTX 4090 with those tricks.

That's an example I just came up with though. There's lots of things like that. But really run a cracker. Try it out.
