Need tips for levels

Hello everyone, this is my first post here and sorry in advance for my English and I guess multiple people asked for this already...

To put it simply, I've reached level 96 and leveling up is extremely slow from now, I'm using exp bonus on tablet mostly abyss, delirium and breach one and do waystone 15 with maximum modifiers, is there something I should know to improve the exp i get ?

Thank you in advance for your time and answers guys

Have a nice day
