Hi, I'm afraid I have to say that although the plugin itself is good, there are a lot of issues with the license and the versions. Furthermore, you can only use the plugin on one server and have to pay to buy additional servers.
The plugin itself is good if you only have one server, but if you have a network, I definitely don't recommend it.

good plugin, dev is friendly and responds very fast, also fixes/adds stuff very fast

Very nice plugin, easy to setup, well optimized. Dev is adding/fixing stuff very fast, he is very nice person in general!

The best duels plugin. Very massive functionality. I really liked it! The developer is very responsive, always helpful. I am satisfied with the purchase!

Great plugin, great creator of the plugin. outstanding support and features 10/10 would recommend for 1.9 Servers, worth the price

this plugin is easy to setup and is very unique and fast support! i recommend you buy this! :D

SCAM! FAKE FEATURES! NO FIREBALL KB CONFIGURABLE! WORST PRACTICE CORE + PRAXI SKID

fake reviews, fake vouchers. this is a scam and everything is fake. DO NOT BUY THIS!

the quality-price plugin is the best, you will not find any other practice core so beautiful and functional at this price. The creator is active and has always helped me in case of difficulty to solve any problem

Amazing plugin! Nice alternative to all current practice solutions! I like that it supports 1.19.4 and works very well.

I recently stumbled upon this practice plugin for Minecraft, and it's a game-changer for our server. What's truly exceptional is the extensive customization it offers, not only for ladders but for all aspects of the server, allowing for a unique and tailored experience. It runs smoothly and receives regular updates. If you're looking to enhance your server, this plugin is a must-have. It deserves a solid five stars!

This practice plugin has been a total game-changer for our Minecraft server. It's easy to install and customize, with endless possibilities for creating practice arenas and engaging player experiences. The performance is exceptional, and the developer's support and updates are top-notch. If you want to take your server to the next level, this plugin is a must-have. Five stars!
