If you are crusader you have the option to use the default PlayerBottomBuffListPlugin plugin, adding these lines to PluginEnablerOrDisablerPlugin:
Code:
Hud.RunOnPlugin<PlayerBottomBuffListPlugin>(plugin => {
plugin.BuffPainter.ShowTimeLeftNumbers = true;
plugin.RuleCalculator.Rules.Add(new BuffRule(483643) { IconIndex = 1, MinimumIconCount = 1, ShowTimeLeft = true, ShowStacks = true }); //P67_ItemPassive_Unique_Ring_948
plugin.RuleCalculator.Rules.Add(new BuffRule(483655) { IconIndex = 1, MinimumIconCount = 1, ShowTimeLeft = true, ShowStacks = true }); //P67_ItemPassive_Unique_Ring_949
} );
Maybe add the stacks later, but they will show inside the icon in the upper corners
