For the St. Patrick’s event, all Tier V to Tier VII tech tree tanks are getting the same discount as they normally would during top of the tree:
- Tier V – 50% discount
- Tier VI – 30% discount
- Tier VII – 30% discount
From Tier VIII to X, it’s a bit lower at 20% instead of Top of the Tree’s 30% discount. So, if you’re planning to get Grille 15 (Top of the Tree on the 20th), you could grab the V to VII now and get a head start.
